TAMPA, Florida -

Ron Paul's delegates haven't been silent at the Republican National Convention. They have fought the Republican Party's rule changes. They have held protests.  But they paused for four minutes Wednesday to see a video tribute to their candidate for President.

The video starts with a narrator calling it "The American Story." It included clips of the Texas Congressman from campaign events and debates. U.S. Senators and Congressmen also said kind words about Paul.

"Whether people want to admit it or not, Ron Paul changed the conversation," said U.S. Sen. Mitch McConnell (R-KY).

"Ron Paul was Tea Party before there was a Tea Party," said U.S. Sen. Jim DeMint (R-SC).

The video also noted that in his 22 years in Congress, Paul has never voted for a tax increase or a debt ceiling increase.

After the video played, Paul's delegates walked out of the convention.

Paul was not invited to speak at the convention. He has not endorsed the party's nominee, Mitt Romney.

Paul's son, U.S. Sen. Rand Paul (R-KY) did speak at the convention later Wednesday. He has endorsed Romney.
