US Rep. Mo Brooks (R.Ala.) was booed at the "Save America” rally in Cullman, Alabama on Saturday during his introduction for former President Donald Trump.
"Now our options are quite simple. Some people are depressed about voter fraud and election theft in 2020. You can forget about that, folks. Brooks advised that you forget about it.
Brooks encouraged the crowd to cheer him on and to keep their voices low as he reminded them to look forward to the general election and the midterm elections. Brooks stood up and said, "Alright. Well, look back at that, but move forward and take advantage."
Brooks currently represents Alabama's 5th Congressional District and is running for a Senate seat that will be held by Sen. Richard Shelby (R.Ala.) in 2022. He is retiring. On April 7, Trump officially endorsed Brooks' candidacy.
