WATCH: Rep. Matt Gaetz vows he’ll vote to nominate Trump to be next Speaker of the House

"After the next election cycle when we take back the House of Representatives, when we send [House Speaker] Nancy Pelosi back to the filth of San Francisco, my commitment to you is that my vote for Speaker of the U.S. House of Representatives will go to Donald J. Trump," Gaetz said to the cheering crowd.

Gaetz also alluded to an ongoing scandal over allegations that he paid underage girls for sex, stating: "They always come out to the fighters."

"I'm a canceled man in some corners of the internet," the Republican lawmaker said. "But in the core of my bones, I'm a Florida man and it feels good to be home."

Article I, Section 2, Clause 5 of the Constitution states that "the House of Representatives shall chuse (sic) their Speaker and other Officers," but does not dictate that the House Speaker must be a member of the chamber. Many legal experts who have examined the issue believe that the founders intended for the House Speaker to be chosen from a pool of elected representatives.

"It would have been unthinkable for the most populous house not to have its leader be part of the representatives who were elected by the people," said Cleveland State University constitutional scholar David Forte, according to NBC News.

The Clerk of the House agreed with the office of the House Historian, which said the House Speaker "has always been (but is not required to be) a House Member."
