President Donald Trump's rally Monday in Houston with U.S. Sen. Ted Cruz has been moved to a bigger venue.

Originally set to take place at the NRG Arena, the event will now be held at the Toyota Center, Trump campaign manager Brad Parscale announced in a tweet Thursday afternoon, describing the demand for tickets as "HUGE and unprecedented." The Toyota Center can hold about twice as many people as NRG Arena — roughly 10,000 versus 19,000.

Trump set expectations high two months ago, when he announced he would come to Texas in October to hold a rally with Cruz at the "biggest stadium we can find." Neither NRG Arena nor the Toyota Center are among the state's largest venues.

The rally is set to begin at 6:30 p.m., and is set to also feature remarks from Gov. Greg Abbott and Lt. Gov. Dan Patrick.

Cruz is being challenged by U.S. Rep. Beto O'Rourke, D-El Paso.
