MEMORANDUM **

Randy Barker (Barker) appeals' from his jury conviction for conspiracy to defraud the United States with respect to false claims, submission of false, fictitious, or fraudulent claims, and money laundering. *709 We have jurisdiction under 28 U.S.C. § 1291. We affirm.

We review for abuse of discretion the district court’s grant of court appointed defense counsel’s motion to be relieved from representation after Barker sued him in a civil lawsuit. See United States v. Rivera-Corona, 618 F.3d 976, 978 (9th Cir. 2010). We conclude the district court did not abuse its discretion. Barker’s lawsuit was sufficient to create a conflict of interest with his counsel. See United States v. Moore, 159 F.3d 1154, 1158 (9th Cir. 1998). To the extent that Barker was without counsel, during the detention/bail hearing, we conclude that this was harmless error. See United States v. Walters, 309 F.3d 589, 593 (9th Cir. 2002). 1

We review de novo Barker’s argument that the district court erred in instructing the jury that the Internal Revenue Service (IRS) is a government agency. United States v. Warren, 25 F.3d 890, 897 (9th Cir. 1994). We conclude that the district court did not err in concluding that the IRS is a government agency as a matter of law. See, e.g., 5 U.S.C. § 101; 31 U.S.C. § 301; 26 C.F.R. § 601.101. However, to the extent that giving the instruction was error, such error was harmless beyond a reasonable doubt. See Schwendeman v. Wallenstein, 971 F.2d 313, 316 (9th Cir. 1992).

Finally, we review the district court’s interpretation of the United States Sentencing Guidelines de novo and its factual findings, including whether a defendant obstructed justice, for clear error. See United States v. Garro, 517 F.3d 1163, 1167 (9th Cir. 2008). The obstruction of justice enhancement applies when a defendant impedes or attempts to impede the official investigation and prosecution of the instant offense. U.S.S.G. § 3C1.1 cmt. 4. We conclude that the district court did not err in imposing the obstruction of justice sentencing enhancement because, based on the facts, it could reasonably infer from the timing of Barker’s actions that he was encumbering the property to avoid a tax lien. See U.S.S.G. § 3C1.1.

AFFIRMED.
