This isn’t Pierson’s first stint with the president; in 2016, Pierson worked as a national — and frequently controversial — spokeswoman for Trump’s presidential campaign. Parscale spoke of the decision to take Pierson on while also mentioning another hiree, Trump’s previous aide John McEntee, saying, “As we build out our operations for the 2018 midterm elections and the 2020 reelection campaign, we are pleased to welcome back two outstanding members of our 2016 team.
