Kimberly Guilfoyle — a former Fox News personality and Donald Trump Jr.'s girlfriend — cracked jokes about her sex life and made sexual offers at President Donald Trump's reelection campaign events, Politico reported.

Guilfoyle, 51, who worked as an adviser on President Trump's reelection campaign team, reportedly engaged in "sexually suggestive" conversations with Trump Jr. that made donors uncomfortable. She also offered to give a lap dance to whoever made the biggest donation at a Trump Hotel fundraiser in December in Washington, D.C., three sources told Politico.

At another event in Jackson Hole, Wyoming, Guilfoyle reportedly offered a hot tub party to whoever raised the most money.

A source also told Politico that at a fall 2018 fundraiser, Guilfoyle said Trump Jr. "liked it when she dressed up as a Dallas Cowboys cheerleader."

Both Guilfoyle and Trump Jr. were in charge of President Trump's fundraising team, which many senior campaign and Republican officials blasted as a disaster. Campaign insiders disclosed the alleged revelations to Politico as part of a deep dive into the possible reasons President Trump fell short in the election.

The finance team failed to collect enough cash and lagged behind Joe Biden's funding numbers, officials told the publication. They also said that they received reports that Guilfoyle berated her employees.  

Trump campaign spokesperson Tim Murtaugh defended Guilfoyle.

"Kimberly Guilfoyle is an excellent fundraiser and was a highly valued asset to the President's team. There was nothing offensive about her presentations in context," Murtaugh told Politico.

Guilfoyle has been at the center of numerous scandals since joining Trump's reelection campaign. In August,  Secret Service records showed that she and Trump Jr. had a two-day visit to Paris in 2018 that cost taxpayers $64,443.

In October, Jane Mayer reported in the New Yorker that Guilfoyle faced sexual harassment allegations by her former personal assistant at Fox News.
