A GOP delegate attempting to mount a challenge to presumptive Republican presidential nominee Donald Trump said Monday she was threatened by angry Trump supporters.

Utah delegate Kera Birkeland said she was confronted by two Trump supporters in a bathroom at the Quicken Loans Arena in Cleveland.

“They said the Utah delegation should lose its police protection, and we should all die,” she told The Huffington Post via email.

Birkeland also posted an account of the encounter on Facebook.

Birkeland was part of a group of delegates who earlier on Monday unsuccessfully tried to force a roll-call vote on convention rules, in an attempt to make it harder to nominate Trump.

Last week, Trump’s New York state chairman, Carl Paladino, sent delegate Stefani Williams an email saying she should be hanged for not supporting Trump.

“You should be hung for treason Stefani,” Paladino wrote. “There will not be a Republican Party if you attempt to replace Trump. I’ll be in your face in Cleveland.”

The recent incidents follow months of threats from Trump supporters toward delegates who have not backed the real estate mogul. Several state delegations, including Utah’s, have been granted additional security at the convention because of the attacks.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S.
