House Speaker John Boehner (R-Ohio) said Sunday morning that "no act, no matter how heinous" would keep members of Congress from doing their jobs.
"The thoughts and prayers of the House and the nation are with Congresswoman Giffords and her family," Boehner told reporters from his home state, calling to mind U.S. District Judge John Roll and the others who were killed or injured when a gunman opened fire at a "Congress on Your Corner" meet-and-greet event by Rep. Gabrielle Giffords (D-Ariz.) on Saturday in Tucson, Ariz.
One of those killed was Giffords's community outreach director, 30-year-old Gabe Zimmerman.
Boehner said that flags on the House side of the Capitol will be flown at half-staff in honor of Zimmerman.
"An attack on one who serves is an attack on all who serve," Boehner said.
The Speaker commended Capitol Police for assisting in the investigation and said he had told FBI Director Robert Mueller that the House stood ready to assist in any way needed.
Boehner confirmed that Majority Leader Eric Cantor (R-Va.) had revised the House schedule next week, including postpoing the healthcare repeal vote, "so we can take necessary action" in response to the Arizona events.
He vowed that the shootings "will not deter" members of Congress from connecting with their constituents and fulfilling their role in office.
"All of us in our roles to our fellow citizens come with a risk," Boehner said.
All lawmakers have been invited to join a 2 p.m. conference call regarding safety measures to come. Family members of lawmakers are also invited to join Democrats and Republicans on the call.
