Before SMITH, BRIGHT, and HANSEN, Circuit Judges.
                          ________________

PER CURIAM.

      This case pends upon the appellant's 150-page motion for a certificate of
appealability.

      Following his guilty plea to the kidnap and murder of a ten-year-old girl, a
federal jury sentenced Keith D. Nelson to death. This sentence was affirmed on
appeal, see United States v. Nelson, 

(8th Cir. 2003), and the Supreme
Court denied certiorari review, Nelson v. United States, 

(2004).
       Nelson then filed his 28 U.S.C. § 2255 motion to vacate, set aside, or correct
his sentence in the district court. The district court determined that no evidentiary
hearing was necessary and that the claims Nelson raised were able to be determined
by the trial record, and the court dismissed both Nelson's § 2255 motion and his
companion motion to disqualify the district judge. Nelson filed a motion pursuant to
Federal Rule of Civil Procedure 59 to alter or amend the judgment entered on his
§ 2255 motion, which the district court denied. He then filed a notice of appeal and
sought a certificate of appealability from the district court, seeking certification on
each of the some 60 separate claims of ineffective assistance of his trial and appellate
counsel asserted in his § 2255 motion, the denial of his recusal motion, and the
separate denial of his motion for additional funding of expert and investigative
services. The district court denied the certificate, and Nelson filed the pending motion
for a certificate of appealability with this court.

       We have carefully reviewed the pending motion and the district court's orders.
We are satisfied that an evidentiary hearing should have been held on some of the
Appellant's claims of ineffectiveness of counsel. Our cases teach that issues regarding
the ineffectiveness of counsel often require a hearing to consider evidence not
disclosed on the face of the trial record. See, e.g., Holloway v. United States, 

, 1357 (8th Cir. 1992) (noting that remand for an evidentiary hearing is
necessary where the record is inconclusive on a claim for ineffective assistance of
counsel); United States v. Dubray, 

, 772 (8th Cir. 1984) (noting in a
direct appeal that ineffective assistance of counsel claims normally "cannot be
advanced without the development of facts outside the original record" (internal marks
omitted)). Under § 2255, a hearing "may be denied only if 'the motion and the files
and the records of the case conclusively show that the prisoner is entitled to no relief.'"
Saunders v. United States, 

, 952 (8th Cir.) (quoting 28 U.S.C. § 2255),
cert. denied, 

(2001). We review for an abuse of discretion the district
court's decision to deny such a hearing, but this review requires de novo consideration
of the validity of the ineffective assistance of counsel claims as a matter of law in

                                            -2-
order to decide if an evidentiary hearing in the district court is warranted. 

cases, the clarity of the existing record on appeal makes an evidentiary hearing
unnecessary," but "[a]bsent such clarity, an evidentiary hearing is required." Latorre
v. United States, 

, 1038 (8th Cir. 1999). Our examination of the claims
asserted in this case convinces us that a fair and just determination of some of them
required an evidentiary hearing to be held. We note that the Government's response
to the original § 2255 motion informed the district court that such a hearing was
necessary.

       Accordingly, we grant a certificate of appealability on the following claims
asserted by Nelson in paragraph 11 of his § 2255 motion, and we remand the case to
the district court with directions to hold an evidentiary hearing on these claims (as
numbered in Nelson's § 2255 motion) and to make its findings of fact and conclusions
of law concerning them:

      A. Allegations of Trial Counsel's Constitutional Ineffectiveness:
      (2) & (3)    Failure to conduct adequate mitigation investigation including
                   failure to move for a continuance to complete one.
            (4) Failure to conduct adequate investigation of defendant's mental
                   health.
            (5) Advising or instructing defendant to decline to submit to a mental
                   health examination by a government examiner.
            (15) Failure to make objections:
                          (e) to allegedly inflammatory and improper comments in
                          the Government's closing argument and rebuttal.
      B. Allegations of Appellate Counsel's Constitutional Ineffectiveness:
            (1) Failure to conduct adequate review of the trial record and the law.
            (2)(c) Failure to raise on appeal the Government's allegedly improper
                   comments in closing arguments.



                                         -3-
       We deny a certificate of appealability on each and all of the other claims
asserted in Nelson's § 2255 motion, and only those claims upon which we have
granted a certificate are permitted to proceed.

       Nelson also appeals the denial of his motion to recuse the district judge. He
need not obtain a certificate of appealability to appeal this ruling because it is separate
from the merits of the § 2255 motion and did not preclude the district court from
ruling on the merits. See Trevino v. Johnson, 

, 177 (5th Cir.), cert.
denied, 

(1999); see also United States v. Falls, 

(8th Cir.
2000) (unpublished) (noting that this court summarily affirmed the denial of a recusal
motion but denied the application for a certificate of appealability). Cf. Slack v.
McDaniel, 

, 484-85 (2000) (describing the circumstances in which a
certificate of appealability should issue for a nonconstitutional procedural issue when
that procedural issue precluded the district court from reaching the merits of the
underlying constitutional claims). We review for an abuse of discretion the district
court's denial of a motion to recuse. United States v. Martinez, 

, 883 (8th
Cir. 2006). Recusal is required if the judge has a personal bias against a party or in
favor of an adverse party, 28 U.S.C. §§ 144, 455(b)(1), or if the judge's "impartiality
might reasonably be questioned," 

Nelson sought recusal on the basis that
the district court made statements in the order denying his request for additional
funding for further expert and investigative assistance that indicated a bias against
him. Specifically, he asserts that the district court prejudged his case by concluding
that the additional funding requested was not likely to lead to a different result, and
Nelson asserts that the district court's bias was shown when the court stated that
Nelson's § 2255 counsel was "attempting to vilify trial counsel's judgment on trial
strategy." (Request for Cert. of App. at 139.)

       Nelson points to no evidence of bias other than the district court's statements
in the ruling denying additional funding. Opinions formed by a judge as a result of
what the judge has observed in earlier proceedings may not be characterized as bias

                                            -4-
or prejudice. Liteky v. United States, 

, 551 (1994). We have stated that
"[r]ules against bias and partiality can never mean to require the total absence of
preconception, predispositions and other mental habits." United States v. Burnette,

, 945 (8th Cir. 2008) (internal marks omitted), cert. denied, No. 07-
11317, 

(U.S. Oct. 6, 2008). The Supreme Court has stated
succinctly that "judicial rulings alone almost never constitute a valid basis for a bias
or partiality motion." 

. The limited exception is where the
circumstances demonstrate "a deep-seated favoritism or antagonism that would make
fair judgment impossible." 

high degree of favoritism or antagonism is not
demonstrated in the statements set forth by Nelson, nor do they indicate that the
district judge is unable to fairly adjudicate Nelson's § 2255 motion. The district court
did not abuse its discretion in refusing to recuse on the basis of statements made in the
order denying additional funding. Because on this record the relevant statutes do not
require the district judge to recuse, Nelson also cannot meet the "more rigorous
standard" of demonstrating a violation of his due process right to an impartial judge.
United States v. Larsen, 

, 1095 (8th Cir. 2005).

       Finally, Nelson argues that the district court abused its discretion in denying his
request for additional funding above the $21,900 already approved by the district
court for expert and investigational services. See 18 U.S.C. § 3599(f). Because we
grant the certificate of appealability on several issues and remand for an evidentiary
hearing, it is unnecessary for us to reach the funding issue at this time. The district
court, in its abundant discretion, should address in the first instance any additional
funding requests that may arise on remand with regard to the issues on which we grant
a certificate of appealability, bearing in mind that Nelson bears the burden of
establishing that further expert testimony is necessary. See 

district
court may authorize expenditures for investigative or expert services that the court
finds to be "reasonably necessary"); United States v. Thurmon, 

, 755 (8th
Cir.) (burden of proof), cert. denied, 

(2005); see also 18 U.S.C.
§ 3599(g)(2) (imposing a statutory limit of $7,500 unless services are of "an unusual

                                           -5-
character or duration, and the amount of the excess payment is approved by the chief
judge of the circuit").

       For the reasons stated, we grant the application for a certificate of appealability
in part, affirm the district court's denial of the motion to recuse, and remand the case
for an evidentiary hearing and the entry of a new judgment on the § 2255 claims on
which we have granted the certificate.
