Here's more on the story, from the Houston Chronicle:

The Houston Police Department will be "fully mobilized" for President Donald Trump's Monday downtown rally, for which at least 70,000 people have signed up despite the venue's roughly 18,000-person capacity, Chief Art Acevedo said Friday.

Police will begin closing off streets around the Toyota Center beginning at about 5:30 a.m., Acevedo said, with closures on Bell, Jackson, La Branch and Polk streets near the arena.

By 7 a.m. Friday, 77,854 people had signed up for the rally, according to a person familiar with the matter. Attendees must have tickets to enter and will be admitted in the order in which they line up.

"Keep in mind that once the capacity is met, you won't get in whether you have a ticket or not," Acevedo said.

Meanwhile, the Trump campaign was not considering moving to a bigger venue, the person familiar with the event said.

Trump is holding the rally with Sen. Ted Cruz, R-Texas, who is facing a re-election challenge from U.S. Rep. Beto O'Rourke, D-El Paso.

Acevedo said HPD had heard unconfirmed reports of a separate nearby rally for O'Rourke that could draw thousands more people.

"We will have many many officers out and about," Acevedo said. "We will have officers on the high ground, low ground, in the air. We will have officers in plainclothes, we will have undercover officers, we will have react teams."

He added that officers from the federal, state and county levels would lend support, with the usual Secret Service presence accompanying Trump.

The police department expects people to "exercise their First Amendment rights in a lawful manner," Acevedo said, including protesters and counter-protesters.

"You would be foolish not to," he said.

Gov. Greg Abbott and Lt. Gov. Dan Patrick, Trump's Texas campaign chairman, will also speak at the rally. Trump is set to begin speaking at 6:30.

People will likely line up overnight for the rally, Acevedo said, adding that the department expects large crowds around the Toyota Center and downtown. He advised people who work downtown to plan accordingly for delays.

Fox News also covered the story:

At least 77,000 people have signed up for President Trump’s Houston rally on Monday to support incumbent Republican Sen. Ted Cruz, who is locked in the Texas Senate battle with Democratic Congressman Beto O’Rourke.

The Houston Chronicle reported that Houston police will be “fully mobilized” for the rally. Attendees must have tickets to enter and will be admitted in the order that they line up, the report said.

"Keep in mind that once the capacity is met, you won't get in whether you have a ticket or not," an officer said.

More than 77,800 people had signed up for the rally by Friday morning, according to The Chronicle. A person familiar with the event told the paper that the Trump campaign was not considering a move to a larger venue.

Absolutely stunning!  

Will the Trump campaign end up switching to the Houston Texans stadium?  They say no, but you have to wonder if the 80,000 seat stadium would be a better fit.

Talk about a rock star.....these are numbers that many of the biggest rock bands can't even hit!

And Trump is doing it night after night after night!

God bless our President!  

He is working tirelessly to Make America Great Again.  Even though he's not running, he knows how important it is to gain a real majority in the Senate, so he's working his tail off to make that happen.

Will the Midterms end up being another historic victory for Trump, just like 2016?

We'll see soon enough.
