The ranking Republican on the House intelligence committee on Tuesday night accused the White House of withholding information on the Fort Hood attack.
Rep. Pete Hoekstra (Mich.) said administration officials delayed briefing members of Congress about the alleged gunman, raising "red flags" about what the White House was hiding.
Hoekstra linked President Barack Obama's handling of Fort Hood to a chain of other GOP criticisms of the president, including the administration's treatment of detainees and an investigation into possible CIA abuse.
"It is a political correctness that is making it unable for us to identify the real threat of homegrown terrorism," he alleged.
Hoekstra warned that "we have similar Hasans" in the country. The Michigan Republican has called for his committee to investigate the incident. Chairman Silvestre Reyes (D-Texas) has so far declined, preferring to wait for the conclusion of the joint FBI-Army investigation.
Obama has ordered a review of all intelligence on Hasan.
