H ouse Speaker Nancy Pelosi had a "please clap" moment while celebrating the passage of the Inflation Reduction Act during an event on the White House South Lawn on Tuesday.

"Mr. President, thank you for unifying and inspiring a vision of a stronger, fairer, safer future for all our children. Your extraordinary leadership has made this glorious day possible," Pelosi said.

Pelosi reminded the audience to cheer.

"That's an applause line," she said.

Audience members then clamored in response. After the apparent stumble, Pelosi regained momentum and continued touting the signature legislation.

Pelosi was joined by President Joe Biden and Vice President Kamala Harris, who also made remarks cheering the enactment of the Democrats' crown jewel legislation last month.

The Inflation Reduction Act entails an array of liberal initiatives, including the expansion of the Affordable Care Act's healthcare premium subsidies, climate and energy initiatives, tax reform, and prescription drug-pricing reform. It includes over $400 billion of spending and is estimated to shrink the deficit by $300 billion over the next 10 years, according to Democrats.

Politicians have been faced with "please clap moments" in the past, in which they have to remind audience members to cheer for something when applause falls flat. Former GOP 2016 presidential contender Jeb Bush had one in 2016 at a campaign stop in New Hampshire.
