Cheney, during an appearance on CBS's "Face the Nation," also said she opposes troop reductions in Afghanistan, which Trump is reportedly considering.

"I think this president has done a lot of very good things, in terms of beginning to rebuild our military, getting out of the Iranian nuclear agreement. But these two decisions would be disastrous," Cheney said.

"They would really in many ways hand victories to our enemies. … It’s a very dangerous path to go down, and we shouldn’t be going down it," she added.

Trump's decision to remove U.S. troops from Syria has sparked bipartisan backlash in Congress.

Cheney, who last month was elected chairwoman of the House Republican Conference, became the latest of several Republicans to criticize Trump over the decision. He has also been criticized by some of his closest allies, such as Sen. Lindsey Graham Lindsey Olin GrahamSenate GOP aims to confirm Trump court pick by Oct. 29: report The Hill's Campaign Report: GOP set to ask SCOTUS to limit mail-in voting Senate GOP sees early Supreme Court vote as political booster shot MORE (R-S.C.).

Graham last week said it would be an "Obama-like" mistake for Trump to remove those troops.

Trump, however, has said for years that he intended to withdraw U.S. forces from Syria and has claimed that he is now doing so because the Islamic State in Iraq and Syria (ISIS) has been defeated in the region.

That claim has been contested by lawmakers, who say there is still work to be done against ISIS.
