WASHINGTON — President Joe Biden on Monday pressed Republicans to take up gun reform legislation after four people were killed and nine people were injured in a mass shooting in Louisville, Kentucky.

The shooter also died at the scene bringing totaling casualties to five.

Biden offered his condolences in a tweet that called the shooting a "senseless act of gun violence."

"Jill and I pray for the lives lost and impacted by today's shooting," he said. "Too many Americans are paying for the price of inaction with their lives. When will Republicans in Congress act to protect our communities?"

It is the 15th shooting this year in which four or more people were killed, according to a USA TODAY/Associated Press/Northeastern University database.

Congress last year passed a bipartisan gun safety law that Democrats say does not go far enough. Biden has said he has exhausted his executive authority and has repeatedly urged lawmakers to ban assault weapons and high-capacity magazines.

He said after a shooting at a Tennessee school at the end of March that state and federal legislators should also require "safe storage" of firearms, eliminate gun manufacturers’ immunity from liability and close so-called gun sale loopholes by requiring background checks for all purchases.
