President Biden will travel to Maine on Friday to pay his respects to the 18 people killed and more than dozen wounded during a gunman’s rampage through a bar and bowling alley in Lewiston, Maine, last week, the White House announced.

Shortly after the massacre, Mr. Biden declared his frustration at the taking of yet more lives in a mass shooting. The gunman, Robert R. Card II, 40, was found dead of an apparently self-inflicted gunshot on Friday, two days after the killings.

“Once again, an American community and American families have been devastated by gun violence,” Mr. Biden said on Friday as the discovery of Mr. Card’s body brought an end to a vast manhunt and lockdowns in the state. “In all, at least 18 souls brutally slain, more injured, some critically, and scores of family and friends praying and experiencing trauma no one ever wants to imagine.”

In a statement, the White House said the president and the first lady would “pay respects to the victims of this horrific attack and grieve with families and community members.” The president will also meet with emergency medical workers, nurses and other officials, the White House said.

The visit will most likely also be an opportunity for the president to repeat his call for a ban on assault weapons and tougher gun control and mental health measures that Republicans and a few Democrats have blocked on Capitol Hill.

In his statement last week, Mr. Biden said, “I once again call on Republicans in Congress to fulfill their obligation to keep the American people safe.” But with Republicans in charge of the House and Democrats only narrowly in control of the Senate, any effort to pass major gun control legislation is all but certain to die.
