Hillary Clinton: Now on Instagram

Now on Instagram: Presidential candidate Hillary Clinton.

The Democratic presidential hopeful sent out her first image on the photo-sharing service Wednesday and poked a little fun at her reputation for favoring pantsuits.

The photo shows a series of red, white and blue outfits arrayed on a rack with the caption "Hard choices." (A play on the title of her recent book.)

Her Instagram profile reads: "Doting grandmother, among other things.”

Clinton will hold her official campaign launch event on Saturday.
