A Pennsylvania Republican lawmaker says he was ordered off the state House floor after Democrat leadership deemed his American flag-themed suit jacket a prohibited "costume" ahead of Independence Day celebrations and the nation's upcoming 250th anniversary, ABC27 News first reported.

State Rep. Eric Davanzo, R-Westmoreland, arrived Tuesday wearing a flamboyant red-and-white striped jacket paired with a blue, star-spangled tie.

House Speaker Joanna McClinton ruled the attire violated chamber dress rules, which require "appropriate business attire," and ordered him to either remove the jacket or leave the floor.

"We don't allow costumes on the floor of the House for any holiday," McClinton said.

"We are very patriotic. That's why we have two huge United States of America flags in the back of the House," McClinton continued.

"You can wear a costume jacket in your office. But on the floor of the House, we have a quorum for all members, no matter the holiday," she added.

Davanzo rejected the characterization, saying, "This isn't a costume. I wear this back home … I'll wear this again next week. I love my country."

"This is just me showing off my patriotism," he added.

Davanzo said, "If I wanted to wear an LGBT scarf, nothing said about that. So if we're going to hold this standard, let's hold it."

McClinton said Davanzo was not singled out, noting members have previously been asked to remove oversized hats and other items from the House floor.

On Facebook, Davanzo wrote, "Kicked off the floor for wearing a Patriotic jacket? That's right, it happened!"

He later added, "I will never apologize for putting patriotism before politics. We love our country."

"We love America, so I'm happy to put this on. I'm proud to wear this," Davanzo said.

Even some Democrats complimented the jacket.

State Rep. Jordan Harris, D-Philadelphia, remarked, "That is a very colorful jacket that the representative is wearing today. Very patriotic, I see, my friend."

Davanzo said fellow lawmakers praised the outfit, saying, "Everybody loved it. They come up, people gave me hugs, shaking my hands, 'Hey, this is great.'"

According to Davanzo, House Whip Mike Schlossberg, D-Lehigh, told him to remove the jacket or leave, and a Capitol security guard later repeated the directive.

"She says it's a costume. He goes, 'Yeah, it's something you wouldn't wear every day,'" Davanzo recalled.

"And I'm like, 'Listen, I would wear this back home, and I'm going to wear it again. America's 250," he continued.

"It's a holiday weekend coming up. Why not wear it?" proposed Davanzo.

McClinton's office defended the decision, saying, "The House Democrats came to Harrisburg this week to do the serious work of passing a responsible budget to benefit all Pennsylvanians."

Davanzo argued lawmakers were focused on the wrong priorities, as Pennsylvania missed its budget deadline for the fifth consecutive year.

"We have an affordability crisis; people can't afford stuff," he said.

"Instead of coming out here and doing the people's work, no, what are we focused on? We're focused on bulls**t issues like this jacket, right? No reason whatsoever," said Davanzo.

"This wasn't a costume. This is something that I truly believe in. I'm a patriot," he emphasized.
