Griner was shot in the leg during the incident but continued standing her ground, according to the citation read at the White House ceremony.
"The assault on June 14 reminded us that evil exists in this world, but it also reminded us that heroes walk in our midst, that love triumphs over tragedy, and that our resolve is stronger than ever", said President Trump. He was unable to attend the ceremony, but his wife, Jennifer, was present. Trump called the Republican congressman "a fighter". This week he was discharged from the hospital and is now beginning weeks of intensive rehabilitation at an inpatient facility.
Congressman Steve Scalise was the most seriously hurt that day.
Officers were first dispatched to the baseball field at 7:10 a.m. on Wednesday June 14, and Officer Jobe, a 16-year Alexandria police veteran, arrived less than two minutes later.
The gunman, James Hodgkinson, had traveled halfway across the country to Washington three months before the attack, and was living in his auto during that time.More news: Partial solar eclipse visible across Alaska

Trump also thanked law enforcement in general "for doing the tough jobs, the risky jobs, and sometimes thankless job with tremendous integrity, devotion, and courage". The assailant wounded Scalise and three others before he was shot dead by police.
Griner and fellow Capitol Police Special Agent David Bailey were at the practice as the security detail assigned to Scalise as part of the House leadership; he is majority whip.
Members of both congressional teams bow their heads for a moment of silence for Rep. Steve Scalise, R-La., before the Congressional baseball game, Thursday, June 15, 2017, in Washington. They included Special Agent Crystal Griner, a Gwynn Oak resident who graduated from a Howard County high school and played college basketball at Hood College.
The members of Congress were practicing for an annual charity baseball game between Republicans and Democrats.
Also on hand to watch the ceremony were Matt Mike and Zachary Barth, a lobbyist and congressional staffer who were also injured in the shooting, and more than a dozen GOP lawmakers. They helped take down the gunman, who had shot and wounded U.S. Rep. Steve Scalise and some congressional staffers, and the officers also prevented further injuries.
