One hundred days have passed since the Republicans took control of the House of Representatives for the first time in four years.

They're touting the promises that they say they've kept to voters, even though their majority didn't get off to the smoothest start.

It took days for Republicans to choose longtime leader Kevin McCarthy, R-Calif., as Speaker of the House. But since the California won the gavel, the GOP majority pushed fast-forward on its agenda.

In February, House Speaker Kevin McCarthy, R-Calif., touted the creation of a Select Committee on Strategic Competition between the United States and the Chinese Communist Party, which received significant support from both parties. He also praised other bills passed by the Republican majority, such as a measure to curb President Joe Biden's use of the United States' Strategic Petroleum Reserve, even though it has little chance of becoming law.

Three major House Republican-backed bills have been passed by the Democratic-controlled Senate and signed into law by President Joe Biden: One ended a COVID-19 emergency declaration; another pushed the administration to declassify information on the pandemic's origins; and the third rejected reforms to the District of Columbia's criminal code.

While House Republicans are touting their successes, one expert says the newly minted majority has yet to deliver on its promises to voters.

"Compared to other Congresses of divided nature as we have right now, it's about on par, especially in this polarized era where it's tough to get agreement," said Casey Burgat, director of the Legislative Affairs program at the Graduate School of Political Management at George Washington University. "But strictly speaking, judging by what they promised their constituents once they got the gavel and sending forward, they've lacked a little muster there."

Republicans have passed bills to enact several of the promises they ran on in last year's midterm elections, including legislation to make oil drilling easier and give parents a greater voice in local schools and block the hiring of 87,000 IRS employees, but those measures have stalled in the Senate, which controlled by their Democratic opposition.

One major House Republican priority passed by the chamber – H.R. 1, the Lower Energy Costs Act, which focuses on domestic energy production – was declared "dead-on-arrival" in the Senate by Majority Leader Chuck Schumer, D-N.Y.

"The Senate is not going to waste our time on a bill that sets America back decades in our transition to clean energy," Schumer said on the Senate floor last month. "All it takes is a brief glance at H.R. 1 to realize it's a giveaway to big oil."

House Republicans also promised to investigate the White House, President Biden and the alleged use of the Department of Justice to target conservatives. Though more hearings are planned, those efforts have not gained much traction. 

"This is the difference between campaigning and governing, where in campaigns you get to talk in broad strokes, you get to be unspecific in terms of what you want to investigate, even though they are able to pick out targets," Burgat said. "But actually getting people to agree to call a hearing, to call witnesses, to do the very laborious efforts of holding a hearing, that's a totally different thing."

House Republicans have also made no progress toward an agreement on raising the government's borrowing limit. Speaker McCarthy declared there would be no agreement unless President Biden agreed to reduce spending, but the Republican conference has yet to present a budget or proposals to cut costs.

"Everyone is warning us that if we don't pass a debt ceiling increase, there will be catastrophic consequences that will have ripple-down effects for everybody, whether they know it or not," Burgat told Spectrum News.

Experts say the country will default on its obligations at some point this summer unless Congress takes action to raise the country's borrowing power. 

The next 100 days for House Republicans could far become more consequential than the first.
