(Bloomberg) -- President Joe Biden will urge Congress to pass gun control legislation in a prime-time address from the White House on Thursday, as a bipartisan group of lawmakers negotiates a possible agreement following a string of high-profile shootings.

“The president will deliver remarks on the recent tragic mass shootings and the need for Congress to act to pass commonsense laws to combat the epidemic of gun violence that is taking lives every day,” the White House said in a statement.

Biden will speak at 7:30 p.m. in Washington. His remarks come the night after a gunman killed four people at a medical office in Oklahoma, and just over a week after a teenager killed 19 children and two teachers at an elementary school in Texas. On Wednesday, a grand jury also indicted an 18-year-old man accused of killing 10 Black people at a Buffalo, New York grocery store last month for a “domestic act of terrorism motivated by hate.”

Senator Chris Murphy, the Connecticut Democrat who has led congressional negotiations, said earlier Thursday that between six and eight Senate Republicans had engaged in conversations on gun control and he hoped to produce a framework agreement by next week that includes funding for mental health initiatives, so-called red flag laws, and background checks.

“We’re talking about a bill that will make a difference, it will save lives,” Murphy told MSNBC.

Ten Republicans would need to join Democrats on the legislation to overcome a likely GOP filibuster.

Biden said earlier in the week that he planned to meet with lawmakers in Congress on gun violence, telling reporters that many instances were “preventable.”

“There’s an awful lot of suffering,” Biden said.

The White House has called for a bill that would increase background checks and restrict assault weapons as well as high-capacity magazines. Aides to Biden have said that there is little he can do through executive action to address guns, and that the White House has held numerous calls with lawmakers on the issue in recent days.
