The rally must begin at 7 pm And at the Alumni Coliseum of Eastern Kentucky University.
Senate Majority Leader Mitch McConnell was spotted by reporters joining Trump in the president's limousine to get to the rally after greeting him on the tarmac.
"On the way to the Grand State of Kentucky – Grand Rally for Congressman Andy Barr – A fantastic guy, he needs his vote for MAGA!" Asset
tweeted Saturday afternoon. "Strong on crime, tax cuts, military, veterans and 2nd A. His opponent will NEVER vote for us, only for Pelosi, Andy has my strongest support !!! in Kentucky. "
The rally in the Bluegrass State is Trump's fourth this week.
Among the possible topics for Saturday's speech might be his meeting in the Oval Office earlier with Andrew Brunson, a pastor who returned to the United States on Saturday after being released from a Turkish jail.
"We had a very tough relationship in the last few months because of what was going on," Trump told the press conference on Saturday. "This is a great step forward to the kind of relationship with Turkey, which can be a great relationship, which I know we are going to have."
Brunson's return is part of the controversy surrounding the disappearance of Washington Post columnist Jamal Khashoggi at the Saudi Arabian consulate in Istanbul last week. The Turkish authorities would have sound and visual evidence of Khashoggi's death, CNN reported Friday, but did not release them to the US, another ally of NATO.
Trump said Saturday that the timing of Brunson's release was a "pure coincidence."
The president also said that he did not want to reopen the Saudi arms agreement that he had negotiated in light of the allegations – an agreement that he estimates at $ 110 billion, but that Saudi Arabia has only followed that for $ 14.5 billion.
