After leaving Fox News Guilfoyle worked for the PAC America First in a fundraising and grassroots capacity.
Former Fox News host Kimberly Guilfoyle is joining President Trump's 2020 campaign as a senior adviser.
Trump's campaign announced the move on Monday, saying in a statement that it is "assembling a world class team of talented individuals to help re-elect Trump."
"President Trump has a clear record of accomplishments and promises kept as he continues to Make America Great Again," Trump's 2020 campaign manager, Brad Parscale, said. "These exceptional additions to the re-election effort will help us take our case to the voters and ensure victory."
Guilfoyle became a top official at the organization just days after parting ways with Fox News last year. Guilfoyle joined the network in 2006 and became a co-host of "The Five" in 2011.
