Less than a week after U.S. Rep. Steve Scalise and four other people were wounded at a congressional baseball practice, U.S. Rep. Mo Brooks announced Tuesday he has introduced a bill allowing lawmakers to carry a concealed weapon.

Brooks, R-Huntsville, was at the baseball practice when the shooting occurred in Alexandria, Va., in suburban Washington. Two capitol police officers, a lobbyist and a congressional staffer were also hit by bullets fired by James T. Hodgkinson.

Hodgkinson was killed at the scene in an exchange of gunfire.

Capitol police officers were at the practice because Scalise, as House Majority Whip, has a security detail.

Brooks pledged in a weekend interview with Fox News to introduce the bill this week.

"The truth is, if Steve Scalise's leadership detail had not been present at last week's practice, many of my colleagues and I might not be alive today," Brooks said in the announcement. "If Congressmen or Senators at the practice had firearms, there is a strong possibility that the shootout would have ended earlier than it did."

Brooks' bill would permit congressional lawmakers to carry a concealed weapon anywhere in the country except the U.S. Capitol or in the presence of the president or vice president.

Brooks' bill is at least the second to be introduced in the House since the shooting. The Washington Post reported U.S. Rep. Thomas Massie, R-Kentucky, proposed a bill that would allow those with conceal carry permits at home to also conceal carry in the District of Columbia.

Brooks was not injured in the shooting but helped care for two people who were shot, including Scalise, R-Louisiana. The FBI found a handwritten note in the pocket of the shooter with a list of members of Congress' names. Brooks' name and his office number in Washington was on the list.

"Last week's shooting at the Republican baseball practice highlighted and reinforced the increasing number of threats faced by Congressmen, Senators, and their families," Brooks said in the announcement.

The need to have the ability to conceal carry, Brooks said, is because members of Congress - excluding leadership - have virtually no protection when they leave the Capitol grounds. By virtue of their political office, Brooks said congressmen are "high-profile targets."

"Surprisingly, because of Washington, D.C.'s restrictive gun laws, congressmen and senators are not allowed to carry a concealed weapon," he said. "That is why today I introduced the Congressional Self-Defense Act to allow lawmakers to conceal carry so that they are better positioned to defend themselves against lone wolf and terrorist attacks."
