Rep. Giffords to resign from Congress this week

WASHINGTON — Rep. Gabrielle Giffords of Arizona announced Sunday she intends to resign from Congress this week to concentrate on recovering from wounds suffered in an assassination attempt a little more than a year ago that shook the country.

"I don't remember much from that horrible day, but I will never forget the trust you placed in me to be your voice," the Democratic lawmaker said on a video posted without prior notice on her Facebook page.
