Republican Ken Paxton is riding high as the Texas attorney general heads into the final days of the U.S. Senate primary runoff against incumbent John Cornyn, now with the weight of President Donald Trump's backing.

The president had long considered backing Senator John Cornyn, but Ken Paxton, the state attorney general, carried the support of the MAGA base.

The president's endorsement is a blow to longtime Sen. John Cornyn, whom Senate Republicans had begged Trump to support.

President Donald Trump made his long-awaited endorsement in the Texas Senate primary set for May 26 between John Cornyn and Ken Paxton.
