An Obama administration official says former Vice President Dick Cheney is intentionally misstating President Barack Obama's terrorism-fighting policies or is ignorant of the facts when he criticizes the White House.

Last week the former vice president said Obama is "trying to pretend" the U.S. is not at war with terrorists. The result, according to Cheney, is that Americans are less safe.

White House counterterrorism adviser John Brennan said Sunday that he has worked for five administrations and that Obama is as determined as anyone to keep the nation safe.

Brennan calls Cheney's comments disappointing and says they do not speak well of the former vice president.

Brennan appeared on "Fox News Sunday" and NBC's "Meet the Press."
