Former Vice President Dick Cheney met Monday evening with the House Republican whip team, but declined to talk to reporters after it ended.
House Majority Whip Steve Scalise (R-La.), who often brings guest speakers to his weekly meetings, invited Cheney, according to his spokeswoman.
Lawmakers in the meeting said Cheney's message focused on national security.
"He talked primarily about national security and defense. And just that the challenge we've got in the world where the president doesn't appreciate the threat," said House Budget Committee Chairman Tom Price (R-Ga.).
Cheney served in Congress, representing Wyoming, from 1979 to 1989. He served as House minority whip for part of his last year.
Late last Friday, Congress passed a one-week bill funding Homeland Security, carrying the debate over funding and immigration into this week. Lawmakers have only five days left to prevent a partial shutdown at the department.
