It's nearing July, and the GOP-led Congress is far behind on the promises that helped it hold the majority in 2016 elections.

A bill to repeal and replace Obamacare and legislation to overhaul the tax code, two central pledges made to voters, are nowhere near finished, despite a plan to get it all done by August.

Must-pass spending bills are far behind schedule as well, and a budget deal that reins in federal spending appears elusive.

Republicans point out that they have made major regulatory changes since taking the majority and the White House. The GOP-led House and Senate, along with President Donald Trump, wiped 14 Obama-era regulations off the books using the Congressional Review Act.

The regulations cleared off the books include the "stream protection rule that critics said would have crippled the coal mining industry, as well as regulations issued under Obama by the Departments of Labor, Education, Interior and Defense, as well as the Secretary of Health and Human Services and the Federal Communications Commission.

Still, the GOP is beginning to worry that they are not accomplishing enough and are running out of time to get anything done.

"I hope we can move faster," Sen. Jeff Flake, R-Ariz., told the Washington Examiner. "We don't have any legislative achievements. We've been able to appoint some good Cabinet members and a good Supreme Court pick, but as for legislation, we're behind."

No one is sure whom to blame for the delay. President Trump's daily tweeting and an unprecedented investigation into his campaign and brief tenure are all the talk on Capitol Hill, which, Sen. John McCain said, "sucks the oxygen out of the room," but doesn't slow down work on major legislation.

But GOP leaders appeared less patient.

Last week, on the way to a meeting with Trump at the White House, reporters asked Senate Majority Whip John Cornyn Texas what message he planned to relay to the president, who over the previous weekend drew criticism for his tweets following a terror attack in London.

Cornyn didn't hesitate in describing what he planned to say to Trump. "We need to get some legislative accomplishments," he said.

Even without the distraction of Trump tweets and hearings over the firing of FBI Director James Comey, the GOP has internal differences that have stopped it from advancing healthcare and tax reform.

Senate Republicans are struggling to agree on the scope of a bill to repeal and replace the healthcare law, and if they do pass a bill, it will be tough to get House Republicans to endorse it as the party fights over how much of Obamacare to keep in place.

The House last week passed legislation to repeal much of the Obama-era financial reform law, which Republicans said would boost the economy by lifting burdensome regulations.

But the bill faces a Democratic filibuster in the Senate, so it's not likely to ever become law.

"The parties seem so far apart," Flake said.

Democrats have begun taunting the GOP for failing to pass major agenda items.

"Republicans have virtually no legislative agenda to advance and no accomplishments to tout," said one memo from the Democratic leadership emailed to reporters.

House Republican leaders last week promoted their legislative accomplishments, pointing out that they have passed 158 bills this year, far more than the average of 91 and more than the 131 bills Democrats passed during the same time period while former President Barack Obama was in the White House.

"So you rate it in modern history, pretty good movement of going forward," said Majority Leader Kevin McCarthy, R-Calif.

Some Republicans said they believe the pace is picking up.

Senate Majority Leader Mitch McConnell last week fast-tracked a legislative vehicle for the Senate healthcare bill, suggesting the chamber would take up a measure soon.

Committee chairs are moving their own priority bills, including Senate Foreign Affairs Chairman Bob Corker, R-Tenn., who is hoping the chamber will pass a bill next week sanctioning both Iran and Russia.

"Actually, I'm beginning to feel some general momentum on the foreign policy side," Corker said. Talks are picking up on a tax reform bill, and the Senate is aiming for a vote on a healthcare bill soon, he added. "I can feel things beginning to gel."
