President Trump is headed to Texas on Monday to campaign for Republican Senator Ted Cruz, who is up for re-election against far-left Democrat Beto O'Rouke.

But according to Trump 2020 campaign manager Brad Pascale, the scheduled rally is being move...to a bigger venue.

Response for tickets to #MAGA rally #Houston Mon 10/22 has been HUGE and unprecedented! This will be an epic rally, so we’re moving to @ToyotaCenter. Want to make sure everyone coming knows the venue changed! — Brad Parscale (@parscale) October 18, 2018

Earlier this week, President Trump expressed his support for Cruz on Twitter and berated his opponent.

Ted Cruz has done so much for Texas, including massive cuts in taxes and regulations - which has brought Texas to the best jobs numbers in the history of the state. He watches carefully over your 2nd Amendment. O’Rourke would blow it all! Ted has long had my Strong Endorsement! — Donald J. Trump (@realDonaldTrump) October 17, 2018

Watched the debate last night & Beto O’Rourke, who wants higher taxes and far more regulations, is not in the same league with Ted Cruz & what the great people of Texas stand for & want. Ted is strong on Crime, Border & 2nd A, loves our Military, Vets, Low Taxes. Beto is a Flake! — Donald J. Trump (@realDonaldTrump) October 17, 2018

Tonight, President Trump is headed to Montana to campaign against Democrat Senator John Tester.
