Former President Donald Trump, still considered by many to be the face of the GOP, spoke at a Republican spring donor retreat Saturday from his Mar-a-Lago resort in Florida. Veering off-topic, he called Senate Minority Leader Mitch McConnell a “dumb son of a bitch" and a "stone-cold loser," according to reports.

Trump said a "real leader" would not have accepted the results of that 2020 election, which was in reference to McConnell recognizing Joe Biden's victory in mid-December.

Trump's comments come amid speculation he will run for president in 2024.

Hundreds of Republican officials found themselves at the retreat listening to Trump rip into McConnell, and other notable figures, such as former President Barack Obama, former Vice-President Mike Pence, Dr. Anthony Fauci and Georgia Gov. Brian Kemp.

Trump also mocked McConnell's wife, Elaine Chao, who served as Trump's transportation secretary. Chao famously resigned from the position after the Capitol riot on Jan. 6.

Neither McConnell nor Chao have issued a public statement.

Trump has made similar remarks to and about McConnell in the past, including in February when Trump said that the Kentucky senator was “a dour, sullen and unsmiling political hack.”

Attendees also noted that Trump went after his former vice-president for not doing enough when it came to overturning the election results, as well as discrediting Dr. Fauci and poking fun at his poor ceremonial first pitch at a Washington Nationals baseball game.

Other notable speakers at Mar-a-Lago included Florida Gov. Ron DeSantis, South Dakota Gov. Kristi Noem and Florida Sen. Marco Rubio.
