WASHINGTON (CNN) -- A House committee announced Tuesday it will examine how the Pentagon ended up spreading false stories about the capture of Army private Jessica Lynch and the death of NFL star-turned-soldier Pat Tillman.

The House Oversight and Government Reform Committee is scheduled to take up those cases in an April 24 hearing, the panel announced Tuesday. The hearing will feature testimony from Lynch and relatives of Tillman, who was killed by friendly fire in Afghanistan in 2004.

The House committee "will examine why inaccurate accounts of these two incidents were disseminated, the sources and motivations for the accounts, and whether the appropriate administration officials have been held accountable," its leaders said in a written statement Tuesday.

The committee, led by California Democrat Henry Waxman, has held several high-profile hearings into the management of the war effort in Iraq and other issues since Democrats took over Congress in January.
