President Donald Trump campaigned in San Antonio on Wednesday night for Ken Paxton, the Republican running for U.S. Senate in Texas. Protesters interrupted him again and again.

At least a dozen demonstrators disrupted the rally at a packed Freeman Coliseum, ABC News reported. CBS News counted at least 10 people who were removed or walked out. At least one person was handcuffed. In one scuffle, a man in a red hat grabbed a protester's hair before other rallygoers separated them. "He's going back home to mom," Trump said after one outburst. "But what he doesn't know is his mom voted for Trump."

It was Trump's third trip to Texas in less than a month. Party officials have put more than $300 million into races in the state, ABC News reported. Texas has not elected a Democratic senator since 1988. But Democrat James Talarico is either slightly ahead or tied with Paxton in most polls, CBS News reported.

Trump called Paxton "perhaps the greatest attorney general in the United States of America." He warned that a Talarico win would turn Texas into a "dirty, failing, crime-ridden third-world dumping ground."

Paxton led the crowd in a chant of "Where is Talarico?" He said the Democrat had not been seen campaigning in Texas for 11 days, Fox News reported. Talarico's campaign said he has the flu and will be back on the trail this weekend. "Ken Paxton has been ignoring Texans this entire campaign," spokesperson JT Ennis said.

Trump also said he will award former pitcher Roger Clemens the Presidential Medal of Freedom. He repeated his support for the death penalty for drug dealers. Talking about the Iran war, he said, "Let them hit San Diego, let them hit Los Angeles. We're not going to let that happen."

Republican Gov. Greg Abbott did not attend. He was scheduled to dedicate a hospital about 330 miles away. Abbott faces a competitive race against Democrat Gina Hinojosa. Texas Democrats used his absence to attack him.

Trump urged supporters to vote early. Early voting in Texas starts Oct. 19.

What we know: Trump has made Texas a repeat stop as Republicans spend heavily to hold it.
What we don't: Whether the money and visits can protect a seat polls show is close.
