The young couple posing in front of the faux Eiffel Tower at the Paris hotel in Las Vegas fit right in, two people in a sea of idealistic Democrats who had arrived in the city in February 2020 for a Democratic primary debate. Large donations to the Democratic National Committee $10,000 each " had bought Beau Maier and Sofia LaRocca tickets to the debate. In fact, much about them was a lie. Mr. Maier and Ms. LaRocca were part of an undercover operation by conservatives to infiltrate progressive groups, political campaigns and the offices of Democratic as well as moderate Republican elected officials during the 2020 election cycle. Using large campaign donations and cover stories, the operatives aimed to gather dirt that could sabotage the reputations of people and organizations considered threats to a hard-right agenda. At the center of the scheme was an unusual cast: a former British spy connected to the security contractor Erik Prince, a wealthy heiress to the Gore-Tex fortune and undercover operatives like Mr. Maier and Ms. LaRocca who used Wyoming as a base to insinuate themselves into the political fabric of this state and at least two others, Colorado and Arizona. In more than two dozen interviews and a review of federal election records, The New York Times reconstructed many of the operatives' interactions in Wyoming and other states ... and spoke to people with whom they discussed details of their spying operation.
