Kirsten Gillibrand, Gabby Giffords Shop Before EMILY's List Dinner (PHOTO)

Sen. Kirsten Gillibrand (D-N.Y.) and Gabby Giffords may not be Congressional colleagues any longer, but they are still good friends.

Gillibrand tweeted this photo Tuesday of Giffords and herself at a Washington, D.C. store. Later they will attend a dinner for EMILY's List, a political action committee dedicated to electing pro-choice Democratic women to office.

Gillibrand and Giffords have been close since before the Arizona shooting that eventually led Giffords to resign from Congress. When Giffords announced in January she was leaving public office, Gillibrand was quick to offer words of support.

"For the past year, Gabby has shown the world the person I have always known -- an extraordinary woman of fierce drive, determination and courage," the senator said in a statement. "Gabby made the right decision for her and her family, but this is just the beginning of the next chapter of her story. I know that Gabby will find other ways to fulfill her calling of public service and continue to lead and inspire the nation."
