The Republican drumbeat to give up the August recess grew on Friday, as 10 GOP senators told Senate Majority Leader Mitch McConnell, R-Ky., that they should stay in order to advance priorities like healthcare, the budget and tax reform.

"We are united in our belief that we must work with a sense of urgency to deliver conservative solutions for pressing legislative issues on behalf of the American people," wrote the group of ten senators, adding that the Senate calendar shows that there are only 33 potential working days before the end of the fiscal year. "This does not appear to give us enough time to adequately address the issues that demand immediate attention."

"Therefore we respectfully request that you consider truncating, if not completely foregoing, the scheduled August state work period, allowing us more time to complete our work," said the letter, which was led by Sen. David Perdue, R-Ga.

Sens. Steve Daines of Montana, Joni Ernst of Iowa, John Kennedy of Louisiana, James Lankford of Oklahoma, Mike Lee of Utah, Mike Rounds of South Dakota, Luther Strange of Alabama, Dan Sullivan of Alabama and Thom Tillis of North Carolina also signed it.

They aren't the first to call for an abbreviated August schedule. The House Freedom Caucus took an official position in early June pressing for Congress to remain in session through the month-long recess, which is supposed to start at the end of July.

The letter was sent days after McConnell announced that there would not be a vote this week on the Better Care Reconciliation Act after it became evident the bill would not have enough support.
