Washington (CNN) -- A bipartisan group of House members will file a lawsuit Wednesday challenging U.S. participation in the Libya military mission.
Meanwhile, President Barack Obama is set to defend U.S. military involvement in Libya to Congress, according to the White House.
The administration will provide a report to address a June 3 House resolution that raised questions about the president's goal in Libya, how he hopes to achieve that goal, why he has not sought congressional authorization for involving U.S. troops abroad and how much the conflict will ultimately cost, National Security Council spokesman Tommy Vietor said.
House Speaker John Boehner, R-Ohio, said in a letter to Obama on Tuesday that the administration could be in violation of the War Powers Resolution if it fails to get congressional authorization by Sunday, which he notes will be the 90th day since the mission began.
The lawsuit, which will be formally announced at a Washington news conference, will cite the War Powers Resolution as well as the role of Congress in protecting taxpayers' money, said Rep. Walter Jones, R-North Carolina, one of the 10 legislators filing it.
