WATCH: Trump's call for earmarks "crazy talk," GOP Sen says

President Trump's support for restoring congressional earmarks is drawing resistance from those in his own party. 

“Maybe we should think about it,” Trump told a bipartisan group of lawmakers at the White House on Tuesday. “Maybe all of you should think about going back to a form of earmarks. You should do it."

But GOP Sen. Jeff FlakeJeffrey (Jeff) Lane FlakeSenate GOP attempts to wave Trump off second Putin summit Senate approves resolution warning Trump not to hand over US officials Flake: Trump's Russia summit ‘truly an Orwellian moment’ MORE (Ariz.), who has openly criticized Trump in the past, quickly dismissed the idea of allowing lawmakers to fund pet projects within large spending bills.

"That’s crazy talk — that’s just — we shouldn’t do it," Flake, who is retiring from the Senate after this year, said. "That is the swampiest thing that anybody could talk about [in] Washington if you’re talking about draining the swamp — you’re putting a firehose and refilling it there.”

Asked if he thought earmarks would make it easier to strike deals, as Trump suggested, Rubio said “No, no, I don't. I don't want to have earmark spending."
