Keys tweeted up a storm during the campaign events she attended during the day. While there, she stopped by the West Philly field office, calling it the “heart [and] soul of the campaign” in a tweet.

Keys joined White House Senior Advisor Valerie Jarrett and Democratic National Committee Chair Debbie Wasserman Schultz (D-Fla.) for the event, according to the Philadelphia Tribune.

“As a mother and a daughter, I know there is too much at stake in the upcoming elections to sit on the sidelines,” Keys said in a statement. “In his three years in office, President Obama has been an advocate for us since day one — from making health care more accessible and affordable to ensuring women can fight for equal pay for an equal day’s work. He has proven that he has the people in his heart! As a new mom, I am going to do everything I can to re-elect the president because this election will determine where we go as a country and what kind of world my child will grow up in.”
