Rep. Gabrielle Giffords of Arizona says on her Facebook page 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.

According to officials in Washington, her resignation is
expected to take effect on Monday.

The Democratic congresswoman was shot in the head last January
as she was meeting with constituents outside a supermarket in
Tucson, Ariz. While her recovery has seemed remarkable, she says on
Facebook she has more work to do to recover, and it is best from
her state if she resigns her seat in the House.

Her shooting prompted an agonizing national debate about
super-charged rhetoric in political campaigns.
