WASHINGTON — More than 200 Republicans who previously worked for either former President George W. Bush, the late Sen. John McCain, R-Ariz., or Sen. Mitt Romney, R-Utah, endorsed Vice President Kamala Harris for president in an open letter Monday obtained exclusively by USA TODAY.

The letter from alums of the three Republican presidential nominees prior to former President Donald Trump comes on the heels of a Democratic National Convention last week in Chicago that showcased Republican detractors of the GOP nominee. At least five former aides to former President George H.W. Bush also signed the letter, which has 238 signatures in all.

A similar group of about 150 anti-Trump former staffers of Bush, McCain and Romney pledged support for President Joe Biden in the 2020 election.
