A former congressional staffer is expected to make “a full recovery” from multiple gunshot wounds sustained during an attack on a GOP softball practice, his family announced.

Matt Mika, who was shot in the chest Wednesday morning by a man armed with a rifle, has undergone several surgeries and “his physicians have reported positive results,” according to the statement.

“Matt will remain in ICU through at least this weekend,” the Mika family said Saturday. “He continues to communicate with us through notes, and even signed the game ball for the Congressional Baseball Game.

James Hodgkinson, who died of wounds sustained in a shootout with law enforcement at the baseball park where the practice was held, had a history of domestic violence and apparently was motivated by hostility to Republicans and frustration over President Trump’s victory in the 2016 election. He had a list of Republican lawmakers in possession when he carried out the attack, according to reports. “I have never said ‘life sucks,’ only the policies of the Republicans,” Hodgkinson wrote in an August 2012 letter to the editor of a local Illinois publication.

House Majority Whip Steve Scalise remains in critical condition after being shot in the hip during the attack, his doctors announced. “I feel a lot more confident and a lot more optimistic than I did two or three days ago,” Dr. Jack Sava, director of the trauma center at MedStar Washington Hospital Center, told reporters on Friday.

Mika’s family asked for contributions to the Capitol Police Memorial Fund, in honor of the security officers who intervened to protect the lawmakers and staff from Hodgkinson’s attack.

“While we know there will be difficult and challenging days ahead for Matt and our family, the physicians and specialists at Matt’s side expect a full recovery,” his family said.
