The White House on Friday suggested that Sen. Roland Burris (D-Ill.), who was appointed to replace President Barack Obama in the Senate, should consider resigning.

Speaking at a White House briefing, Press Secretary Robert Gibbs said in an answer to a question that the embattled Senator this weekend should either come up with a good explanation for discrepancies between his testimony before an Illinois impeachment committee and subsequently discovered facts, or he should think about his future.

Burris has acknowledged not fully disclosing all of his contacts with the office of former Illinois Gov. Rod Blagojevich (D) during the period before Blagojevich appointed him Senator.

The Legislature has since removed Blagojevich from office for allegedly trying to profit from the Senate vacancy, and on Friday, Blagojevich’s successor, Gov. Pat Quinn (D), called on Burris to resign.
