President Donald Trump announced Monday his plan for a political rally in Casper, Wyoming.

The president is expected to rally with Harriet Hageman, a Republican primary challenger to Rep. Liz Cheney (R-WY).

The rally is scheduled for Saturday, May 28, 2022, at 4:00 PM MDT on Memorial Day weekend.

Hageman was chosen by Trump in September 2021 to challenge Cheney despite a crowded field of interested candidates.

“Unlike RINO Liz Cheney, Harriet is all in for America First. Harriet has my Complete and Total Endorsement in replacing the Democrats’ number one provider of sound bites, Liz Cheney,” Trump wrote at the time. “Make America Great Again!”

Many of the top challengers to Cheney dropped out to support Hageman, but not State Sen. Anthony Bouchard, whose fundraising has slowed since Trump chose not to endorse him.

Cheney has raised more than $10 million for her race, with $6.8 million cash on hand.

The daughter of former Vice President Dick Cheney has become the darling of the media and Democrat elite since she vocally protested the majority of the Republican party supporting Trump.

She has also won support from anti-Trump Republicans.
