Although President Donald Trump has followed through on many of his campaign promises, he has yet to push several of his most important pieces of legislation through Congress: the repeal and replace of ObamaCare, tax reform and raising the debt ceiling.

"The problem for the president, for the Republicans is that the policies are being held up by the fact that Republicans can't agree among themselves,"  Charles Krauthammer said on "Special Report" tonight.

He pointed out that health care reform was stalled by internal party disagreements in the Senate, and he predicts it will be the same with tax reform.

"This is a problem. You've got one party with control of all the elements of power," Krauthammer said.

He added that when the Democrats had that control during former President Obama's first term, they passed an enormous stimulus package and totally "remade" health care policy.

"You can agree with the results or with the legislation or not, but the effectiveness of what they did is unmistakable," Krauthammer said, concluding that hasn't happened yet with Republicans during the Trump administration.
