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

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.

South Carolina Sen. Tim Scott, who leads the Senate GOP campaign arm, gave an animated speech, criticizing a slate of Democratic candidates before concluding that the only way to keep "dangerous, radical, weird" out of the Senate is a "united Republican Party."

"Standing with our President Donald J. Trump," he shouted, raising both hands in the air. "Stand for the President Donald J. Trump. This is a battle for the heart of our nation. I said the heart of our nation."

Scott pulled open his jacket and pounded his chest as he shouted, "The Democrats' extreme candidates won't rip that heart out of our chests. They hate our culture. They hate what it means to be American. Hear me Dallas? Not on our watch. We won't back down. We will not grow weary. Are you with me?"

Scott went on to criticize Texas Democratic Senate candidate James Talarico for believing that God is non-binary, comments that Talarico has walked back, and took a number of stabs at Michigan Democratic Senate candidate Abdul El-Sayed, saying that he "panders with terrorists."

Texas Attorney General Ken Paxton, running in one of the most-watched Senate races this cycle, praised Trump and targeted his opponent, Democrat James Talarico.

Paxton attacked Talarico for his past comments, including saying that God is non-binary and called him the most "radical Democrat" in the history of Texas.

"He calls himself a Christian who hates Christianity, said God is non-binary. I must have missed that verse in the Bible," Paxton said.

When asked about his comments in recent months, Talarico has said that he missed the mark.

Despite Paxton speaking in his home state, the crowd was not as enthusiastic for him as other candidates. The Talarico attacks got him big cheers, but the parts of his speech focused on policy and platform had the crowd quiet.
