Republican Sen. Tom Cotton will not run for president in 2024, source says

Republican Sen. Tom Cotton of Arkansas won't be running for president in 2024, a source close to Cotton confirmed to CBS News on Sunday. 

Cotton has been calling donors and friends to inform them of his plans to not run. Politico first reported the news.

Cotton, who was first elected to the Senate in 2014, is one of the Republican party's rising stars. He has pushed a "tough on crime" agenda, including saying on "CBS Mornings" last week that "we need to crack down" following the attack on Paul Pelosi, the husband of House Speaker Nancy Pelosi.
