After the Republicans were able to narrowly hold onto their majority in the Senate Tuesday night, according to Fox News projections, Sen. Lindsey Graham (R-S.C.) praised President Trump for his enthusiasm leading up to the midterms.

The GOP will control over federal judicial appointments with retention of the Senate -- including Supreme Court nominations.

Graham said that "the conservative judicial train will keep running" and that the GOP "had a good night in the Senate."

"I'm excited. It means that judges keep moving forward on the conservative side and it's going to put some pressure on all of us to up our game," he said.

With the Democrats projected to gain control of the House, Graham gave a word of "advice" to his opposing party.

"Been there, done that with Clinton. Didn't work for us. I would think twice about it. It will blow up in their face," he said.

He added that there's a "natural fit" for both parties to build out the country's infrastructure, and agreements could potentially be made on the topic of immigration.

"The reason we won is, I think, [Justice Brett] Kavanaugh united our party, the caravan was a front to our sovereignty, the economy was good and President Trump worked his butt off to get out the Republican base vote," he said.

He said that if Democrats want to "stiff-arm" Trump, "they'll pay a price in 2020."
