OPINION
PER CURIAM.
In December 2006, Petitioner Kevin Woodruff, a federal prisoner who, at the time, was incarcerated at USP-Lewisburg in Pennsylvania, petitioned the District Court for a writ of habeas corpus pursuant to 28 U.S.C. § 2241. In January 2009, Woodruff petitioned this Court for a writ of mandamus, requesting an order compelling either the Respondent to answer Woodruffs June 2008 motion to supplement his habeas petition or the District Court to act upon his habeas petition. On March 12, 2009, 2009 WL 703200, the District Court denied Woodruffs habeas petition. Given that Woodruff has now received one of the alternative forms of relief he seeks in his mandamus petition — a ruling on his habeas petition — we will deny his mandamus petition as moot.
. Woodruff has since been relocated on multiple occasions, and currently is incarcerated at USP-Big Sandy in Kentucky.
. Woodruffs petition also seeks either a declaratory judgment or preliminary injunction prohibiting the enforcement of 18 U.S.C. § 4081, which he claims was enacted by less than a quorum of Congress and is therefore unconstitutional. Woodruff has not established that this claim warrants mandamus relief. See Hahnemann Univ. Hosp. v. Edgar, 74 F.3d 456, 461 (3d Cir.1996) (“The writ of mandamus is a drastic remedy that a court should grant only in extraordinary circumstances in response to an act amounting to a judicial usurpation of power.” (citations and internal quotation marks omitted)).
