The departure from the race came less than 90 days before the Iowa caucuses, on which Mr. Pence had staked his candidacy.
But while Iowa is a more difficult early state in the Republican primary contests for Mr. Trump than some of the others, the former president remains dominant there.
Mr. Pence is the highest-profile candidate to leave the race, and the first of those who had met the Republican National Committee’s criteria for the primary debates.
Mr. Pence’s campaign recently reported more than $600,000 in debt.
But Mr. Pence, a former governor of Indiana, struggled mightily to raise money, never gaining traction in the polls that his former running mate has dominated.
