Live updates: Trump promises $5K 'dividend' to all adult Amercians if GOP keeps control of Congress

Trump promised the convention crowd that he'll issue a $5,000 "dividend" to all adult Americans if Republicans keep control of the House and Senate in the midterm elections.

"Because of our tremendous strength and success economically, I will issue a dividend to every adult citizen in the United States of America for $5,000," Trump said, likening it to what "a successful company will do a cash distribution to its shareholders."

Trump said the only condition attached is that the money must be spent in the U.S.

As the president began his speech, there were several rows of empty seats in some pockets in the American Airlines Center.

Trump often brags about crowd size and loves to see a packed arena.

Trump told the crowd at American Airlines Center that Republicans need to vote like he's on the ballot in November.

"This has been the most successful two years, financially and every other way in the history of the presidency," Trump said.

"So I'm asking you to pretend that I'm on the ballot. I'm on the ballot. I'm on the ballot. Just one more time, because if we lose, you're going to lose your border. You're going to lose your tax cuts. You're going to lose your safety and security. you're going to lose your wealth. Our country is going through hell. You will be going through hell, just like you did just two years ago," he said.

One of the major themes of the convention is Republicans pushing what they call common-sense policies compared to Democrats and Florida GOP gubernatorial candidate Rep. Byron Donalds discussed the commonality that Texas and Florida share in building policies based on that.

"Florida and Texas have something absolutely essential in common. Our two states prove every single day that Republican policies built on common sense work for the American people," Donalds said.

Turning his attention to Democrats, Donalds said that they created the affordability crisis and that Americans should not trust them to fix it.

"But let me ask all of you here tonight: Do you let the arsonist become the firefighter? Because make no mistake, the Democrats created the inflation that's crippling families, and we, the Republican Party, we have the resumé and the credentials and the plans and the policies to get our country back on track," Donalds said.
