Guilfoyle, who began dating Trump Jr. about a year ago, announced the news Monday on Instagram with a photo of her standing between her boyfriend and her new boss.
“America’s continued success depends on @realDonaldTrump getting re-elected and continuing his #MAGA policies,” she wrote in the caption. “That’s why I am absolutely THRILLED to announce that I’ll be joining the Trump campaign as a Senior Advisor! It’s time to get to work and WIN for America in 2020!”
Page Six reported in May 2018 that Guilfoyle and Trump Jr. had been “dating for a few weeks” as he divorced then-wife Vanessa Trump. Guilfoyle was a co-host on Fox News’ “The Five” at the time, but the network announced her departure that July.
