Six House members asked President Obama to fire James Clapper, the Director of National Intelligence who admitted to giving Congress the "least untruthful" answer he could about National Security Agency programs, in a letter sent Monday.

“The continued role of James Clapper as Director of National Intelligence is incompatible with the goal of restoring trust in our security programs and ensuring the highest level of transparency,” the lawmakers -- Reps. Darrell Issa, R-Calif.; Alan Grayson, D-Fla.; Ted Poe, R-Texas; Paul Broun, R-Ga.; Doug Collins, R-Ga.; and Walter Jones, R-N.C. -- wrote. “Director Clapper continues to hold his position despite lying to Congress, under oath, about the existence of bulk data collection programs in March 2013.”

Clapper gave the offending answer during a Senate hearing in March. "Does the NSA collect any type of data at all on millions or hundreds of millions of Americans?" Sen. Ron Wyden, D-Ore., asked Clapper.

"No, sir," Clapper replied, before NSA leaker Edward Snowden demonstrated that the agency collects the records of phone calls made within the United States as part of a bulk data collection program.

In an ensuing interview with NBC's Andrea Mitchell, Clapper described his reply as the "least untruthful" answer he could give in that setting.
