President Trump spoke at a rally in Kansas on Saturday night, praising his newly confirmed Supreme Court pick Brett Kavanaugh while also slamming Democrats and urging people to vote Republican in the upcoming midterm elections.

Upon taking the stage, Trump told the crowd in Topeka that he was "thrilled" to be with them on a "truly historic night."

The president was in Kansas to support Kris Kobach, the GOP nominee for governor, as well as political newcomer Steve Watkins, a Republican seeking to succeed retiring U.S. Rep. Lynn Jenkins.

The president praised Republican senators and Kavanaugh, calling him "a man of great character and intellect," while also condemning Democrats for what he described as their "disgraceful campaign" against him.

"The radical Democrats have turned into an angry mob" who have thrown to the side "every notion of fairness, of justice, of decency and of due process," Trump said.

He went on to urge the crowd to go to the polls next month, telling them they "have a chance to stop the radical Democrats" by electing Republicans to Congress.

"The Democrats are willing to cause such destruction in the pursuit of power, just imagine the devastation they would cause if they ever obtained the power they so desperately want and crave," Trump said.

He also applauded GOP Sens. Chuck Grassley and Mitch McConnell, saying both are "great," as well as Sen. Susan Collins, who announced her support for Kavanaugh on Friday in a 40-minute speech on the Senate floor.

"How good was Sen. Susan Collins yesterday?," Trump asked the crowd.

During a post-rally interview on Fox News' "Justice with Judge Jeanine," host Jeanine Pirro asked Trump about controversial comments he made earlier this week at a rally in Mississippi, questioning the sexual assault allegations made by Kavanaugh accuser Christine Blasey Ford.

"Well, there were a lot of things happening that weren’t correct. They weren’t true. And there were a lot of things that were left unsaid. And I thought I had to even the playing field because it was very unfair to judge -- now I can, you know, very nicely say Justice Kavanaugh," Trump said. "It was a very unfair situation. So I evened the playing field. And once I did that, it started to sail through. He was treated very, very unfairly."

Earlier Saturday, the Senate voted 50-48, mostly along party lines, to confirm Kavanaugh to the nation’s highest court.

During the rally, the president also accused Democrats of supporting sanctuary cities and of wanting to strip funding from U.S. Immigration and Customs Enforcement (ICE).

"Democrats also support deadly sanctuary cities that release violent predators and bloodthirsty killers, like MS-13, into our communities," Trump said. "Republicans believe our country should be a sanctuary for law-abiding Americans, not criminal aliens."

He said members of the GOP "stand proudly" with law enforcement, Border Patrol and ICE, who he added are "not treated properly."

"MS-13 doesn’t like ICE. That’s why I like ICE," Trump said.

Separately, Trump took aim at a few Democrats, including Sens. Richard Blumenthal, D-Conn., and Elizabeth Warren, D-Mass., the latter of whom he referred to as "Pocahontas" because of her claims of Native American ancestry.

"I’ve got more Indian blood in me than Pocahontas -- and I’ve got none," Trump said.

Following the rally, Warren fired back at Trump on Twitter.

"Hey @realDonaldTrump, hope you’re having fun at your rally. Too bad you’re the least popular incumbent president in modern history," she tweeted. "And in the meantime, we are coming for your pathetic rubber-stamp Republicans in Congress in 31 days."
