President Donald Trump on Tuesday evening criticized Amy McGrath, the newly announced Democratic challenger to Senate Majority Leader Mitch McConnell (R-Ky.) rebuked her for comparing his election to 9/11.

“Democrats are coming after our great Kentucky senator, Mitch McConnell, with someone who compared my election to September 11th,” Trump tweeted Tuesday. 

“Why would Kentucky ever think of giving up the most powerful position in Congress, the Senate Majority Leader, for a freshman Senator with little power in what will hopefully be the minority party. We need Mitch in the Senate to Keep America Great!!” 

McGrath has complained about Trump’s White House victory, saying it felt similar to the aftermath of the Sept. 11, 2001, terrorist attacks.

“And that morning I woke up like somebody had sucker punched me,” she said at a November 2017 candidate forum, according to the Courier Journal. “I felt like, ‘What has just happened to my country?’ The only feeling I can describe that’s any close to it was the feeling I had after 9/11.”

Amy McGrath, a Marine combat aviator who narrowly lost a House race to an incumbent Republican in Kentucky, said Tuesday she will be trying to defeat Mitch McConnell.

McConnell responded quickly in a Twitter message that presaged what a race between him and McGrath would look like. The tweet strung together a series of quotes from McGrath that depicts her as an out of touch liberal who also opposes Trump, notably his call for a U.S.-Mexico border wall.

McConnell’s campaign manager Kevin Golden said McGrath lost in 2018 “in a Democratic wave election because she is an extreme liberal who is far out of touch with Kentuckians.”

McGrath lost to Rep. Andy Barr by 3 percentage points in the 2018 midterm election, a race that she had been so confident of winning that she was working on her victory speech as the first returns came in.

Schumer worked hard to persuade McGrath to run against McConnell. Several other would-be recruits, including former Georgia House Minority Leader Stacey Abrams, declined his overtures, and others, like former Colorado Gov. John Hickenlooper, former Texas Rep. Beto O’Rourke, and Montana Gov. Steve Bullock, passed on Senate races to run for the Democratic presidential nomination.
