Senate negotiators are working against the clock to reach a final agreement on gun-control legislation. After reaching an agreement earlier this month on a framework for the bipartisan agreement, negotiators are attempting to translate the agreement into legislative text, which must be completed by Tuesday to keep the vote scheduled for this week.

They have until the end of this week if they want to pass the bill quickly. The Senate will take a two-week break beginning next week.

According to ABC News, two specific provisions are impeding negotiations. One focuses on providing federal grants to states to enforce so-called "red flag" laws, which allow authorities to temporarily remove firearms from people who threaten violence.

The other sought to close the "boyfriend loophole," which allows convicted domestic offenders to purchase firearms even if they are not married to their partner, even though spouses who perpetrate domestic violence are.

Senators have been negotiating gun control measures for weeks, following a string of mass shootings, including the massacre of 19 children and two teachers at an elementary school in Uvalde, Texas, that sparked a public outcry for action on guns.

On June 12, the group announced an agreement on the framework for a bill, which key Republican senators, including Minority Leader Mitch McConnell (R-Ky.), said they supported, sending a strong signal that the potential bill would garner the 10 Republican votes needed to overcome the Senate filibuster.

However, lawmakers have been bogged down in final details, such as how to close the boyfriend loophole, which has cast doubt on whether a deal on the bill's language will be reached.

Cornyn was booed during his speech at the Texas Republican Convention last week, despite claiming to have taken Democrats' "gun-grabbing wishlist off the table."

Meanwhile, President Joe Biden appeared to be optimistic about the status of the talks while speaking to reporters in Rehoboth Beach, Delaware, on Monday.

"I'm confident that... a serious, serious negotiation is getting close to fruition," Biden said.

He acknowledged that some state laws have been effective in reducing gun violence, but he concluded that "it would be better if we had better regulation of firearms sales, nationally and nationally mandated."

Last week, Senate Minority Leader Mitch McConnell (R-KY) confirmed his support for the gun-control agreement. With his support, the bill receives at least 61 votes, one more than is required to overcome a Senate filibuster.
