"It's not just a phrase, it's a movement, right? And people are sick and tired of this administration and all the destructive things they've done, especially to our economy, and the way that they express that right now is with ‘Let's go, Brandon,’" Boebert's communication director Ben Stout told The Hill in a statement.

"The meeting with President Trump went phenomenal. The dress made President Trump smile. He loved it. Congresswoman Boebert has been a leader of the Make America Great Again movement and a leader for pushing President Trump's agenda forward in Congress. And so the meeting went phenomenally well," Stout said. 

"They discussed how destructive the Biden administration has been and the importance of putting President Trump’s policies in place so that we can get America back on track," he added.
