Lawmakers, including Democratic National Committee Chairwoman Debbie Wasserman Schultz (D-Fla.), welcomed Biden to the social media network.
Welcome to Twitter @drbiden!— D Wasserman Schultz (@DWStweets) April 22, 2013
Michelle Obama initially joined Twitter under her personal name in January 2012, in an account created by the Obama campaign. In January of this year, her office set up an official handle — @FLOTUS — for her White House duties.
Joe Biden joined Twitter in July 2011; President Obama announced he would begin personally tweeting from his account a month earlier.
