Pence Challenges Trump with 2024 Presidential Bid Filing.

Former Vice President Mike Pence has filed paperwork to run for president in 2024, setting up a challenge to his former boss, Donald Trump. Pence will formally launch his bid for the Republican nomination with a video and kickoff event in Des Moines, Iowa, on Wednesday. While Trump is currently leading the early fight for the nomination, Pence supporters see a lane for a reliable conservative who espouses many of the previous administration’s policies but without the constant tumult. Pence's team sees Iowa and its evangelical Christian voters as critical to his potential path to victory.
