A sea of red "Make America Great Again" hats flooded the Bluegrass State on Saturday as supporters cheered for President Donald Trump as he blasted liberal policies, praised Kentucky politicians and claimed that open borders would "kill us all."

Trump was in Richmond to campaign for Kentucky Republican Rep. Andy Barr, who is challenging former Marine fighter pilot Amy McGrath in a hotly contested congressional race for District 6.

Amid all of the political insults, policy points and applause lines, here are five of the most notable things Trump said Saturday night.

Democrats want sanctuary for "thugs"

"Democrats want to open America’s borders and turn our country into a friendly sanctuary for murderous thugs from other countries who will kill us all," Trump said.

Trump's calls against Democratic compromises to undocumented immigration in the United States were met with chants of "build the wall" and thunderous applause from the packed crowd at Eastern Kentucky University.

“They [Democrats] will open our borders to a bunch of ruthless gangs,” Trump said. “The Democrats have become the party of crime, the Republicans are the party of safety.”

Trump decried New York Sen. Chuck Schumer's idea of a lottery to offer legal status to the United States by claiming foreign countries weren't "sending us their finest."

“We want great people who respects our country, and who want to work," Trump said.

Trump flaunts friendship with Rand Paul and Mitch McConnell

Despite butting heads with them in the past, Trump praised Kentucky's Republican Senators.

Trump praised McConnell's hustle to rapidly appoint conservative-minded justices.

“There’s nobody tougher,” Trump said. “He’s a tough cookie ... he’s Kentucky tough … He got us a man who will be one of our great Supreme Court justices."

Trump also called Paul a "good friend" and urged the "young and spry" politician to jump on stage with him.

The tone is different from Trump's comments toward Kentucky's junior senator in 2015, when he called him "a spoiled brat without a properly functioning brain" and said he "didn't get the right gene."

Investigation into Kavanaugh was a 'national disgrace'

Playing off McConnell and Paul, “What the Democrats did to Justice Brett Kavanaugh is a national disgrace,” Trump said to thunderous applause.

He praised Kentucky's senators as being instrumental in backing newly confirmed Supreme Court Justice Brett Kavanaugh and decried the investigation into allegations of whether the judge had sexually assaulted women in high school and college.

"We stood with him all the way,” Trump said. “Because we knew the facts. And Rand Paul and Mitch McConnell stuck with him too.”

'Coal is thriving,' but studies show otherwise

In playing to Barr's Kentucky voting base, Trump restated his commitment to grow the Bluegrass State's coal industry.

“We have ended the war on clean, beautiful coal,” Trump said to cheers. “We are putting our miners back to work like never before. ... Everyday we are living by our motto, 'promises made, promises kept.'"

Trump also said Barr's opponent "wants to decimate your now thriving coal industry.”

But a recent study from the Kentucky Energy and Environment Cabinet in August shows otherwise. The number of coal jobs averaged 6,238, which is down 0.9 percent from the first three months of the year and down 4.8 percent during the same period in 2017.

Trump taunts McGrath: 'Who is [Barr] running against?'

Trump's main purpose on Saturday evening was to back Barr. And while he overwhelmingly praised the Republican incumbent, he also took aim at the Marine fighter pilot.

“Who is he running against?” Trump said, taunting the veteran whose candidacy has made national headlines. “An extreme liberal chosen by Nancy Pelosi, Maxine Waters and the radical Democratic mob

He quickly pitted the Democratic challenger against the crowd and painted her as an being a fierce opponent of his administration's goals.

“Amy supports a socialist takeover of your healthcare, she supports open borders, she needs the tax hikes to cover the through the roof garbage you want no part of,” Trump said.

McGrath responded after the rally.

"Mr. President, you clearly don't know me," McGrath said. "Yet."
