In the wake of theat an event held by Democratic Rep. Gabrielle Giffords, the House has postponed all legislative business for the next week.
This most importantly includes the vote to repeal President Obama's health care law, which was scheduled for Wednesday and would have be the first major vote of the House since Republicans took control last week.
A statement from Eric Cantor (R-Va.), the House Majority leader, announced tonight that all legislation scheduled to be considered by the House next week has been postponed "so that we can take whatever actions may be necessary in light of today's tragedy."
"Our nation was shocked by the tragedy in Arizona earlier today," Cantor added in his statement. "Congresswoman Giffords serves Arizona's 8th District with distinction and thoughtful leadership, and it is horrifying that she was exposed to such violence at an event designed to reach the people she represents... Along with our nation, this institution has suffered a horrible tragedy."
At least six people were killed in today's attack, allegedly carried out by 22-year-old Jared Loughner. Federal Judge John M. Roll was among those killed. Giffords was shot in the head and is in critical condition following surgery.
