Utah Republican Sen. Mitt Romney will fundraise for endangered Wyoming Rep. Liz Cheney at a Virginia event in March where attendees are required to be fully vaccinated.

The fundraiser, scheduled for March 14, will be held at the home of well-connected Virginia Republicans Bobbie and Bill Kilberg who opposed then-candidate and businessman Donald Trump in 2016, according to an invitation reviewed by The Federalist.

“All attendees must be fully vaccinated against COVID,” the event invite reads for a beneficiary who voted in December to expand the federal government’s surveillance tracking citizens’ vaccination status.
