With one week to go before Election Day and early voting already underway, President Donald Trump has made a long-awaited endorsement in Texas' Republican primary runoff for the U.S. Senate.

Donald Trump has endorsed Ken Paxton in the Texas Republican Senate runoff, praising him as a loyal warrior for the MAGA movement.

The contest, the most expensive primary in the history of the House of Representatives, had been widely seen as a key test of President Trump's decade-long grip on the Republican Party.
