U.S. Capitol Police are investigating a report that Rep. Andy Harris, R-Md., tried to take a gun onto the house floor Thursday, a department spokesperson said.
"One security official present saw a firearm on the person of Rep. Harris and relayed that to his superiors," a Capitol official told NBC News.
"To be clear, Rep. Harris did not enter the Floor."
They have become a flashpoint among some Republican members, and they have at times created tension with police.
The Capitol official added that House members are allowed to carry firearms "in the halls and on Capitol grounds, including the Capitol Building but not the Floor," adding that "ammo has to be separately compartmentalized."
