Democratic Rep. Al Green of Texas said Tuesday he plans to force a vote in the House next week to impeach President Trump following the president's comments on NFL players who kneel during the national anthem.

"Mr. Speaker, I rise to denounce these comments that have been made because they have brought discourse to a new low. Mr. Speaker, this is a level of indecency that is unbecoming the presidency. Mr. Speaker, I rise to say to the world that this is not what America is all about," Green said during a floor speech Tuesday. "Calling people SOBs, and we know what a B is. It's a dog. Mr. Speaker, I rise because my heart tells me I must do something.

"So Mr. Speaker, I denounce the comments that were made, and I rise to announce that on next week, Mr. Speaker, I will bring a privileged resolution before the Congress of the United States of America," Green added. "I will stand here in the well of Congress, and I will call for the impeachment of the president of the United States of America."

During a rally for Republican Sen. Luther Strange in Alabama on Friday, Trump said NFL owners should fire any player who kneels for the national anthem.

"Wouldn't you love to see one of these NFL owners, when somebody disrespects our flag, to say, 'Get that son of a bitch off the field right now, out, he's fired. He's fired,'" the president said.

Trump has continued to rail against the NFL and athletes who kneel on Twitter, and on Tuesday, he called on the league to implement a new rule prohibiting players from protesting during the national anthem.

The president's comments were rebuked by NFL team owners, coaches and players, and many kneeled or linked arms when the national anthem was played before Sunday's game. Three teams decided not to take the field, waiting instead to leave the locker room or the tunnel until "The Star-Spangled Banner" was over.

Democrats also denounced Trump's comments. So far this week, two Democratic members of Congress — Reps. Sheila Jackson Lee of Texas and Mark Pocan of Wisconsin — have kneeled during speeches on the House floor in solidarity with NFL players.

Green is the first, however, to call for Trump's impeachment over the president's comments. Green and Rep. Brad Sherman, D-Calif., filed an article of impeachment against Trump in July that accused the president of obstructing justice during the federal government's probe into Russian meddling in the 2016 election.

"I rise not as a Democrat, or a Republican. I rise today, Mr. Speaker, not as a liberal or a conservative. Mr. Speaker, I rise today as a proud American, a person who believes in his country, who salutes the flag, and says the Pledge of Allegiance, and sings the national anthem," Green said. "I rise today, Mr. Speaker, to make comments that I never thought I'd have to make in the well of the House of Congress. I rise today to defend, denounce and announce. Mr. Speaker, I rise to defend any mother who has been called a dog because her son engaged in peaceful protest. I rise, Mr. Speaker. I rise today, Mr. Speaker, to defend any son who is called the son of a dog because he engaged in peaceful protest."
