WASHINGTON (AP) — It seems like everyone who saw Prince perform at the White House this weekend was talking about it on social media, except for the White House. White House spokesman Josh Earnest refuses to confirm that Prince played a party for President Barack Obama and his wife, Michelle. Earnest will only say the Obamas threw the party on their own dime but won’t say how much it cost. The Reverend Al Sharpton tweeted it was awesome to see Prince and Stevie Wonder perform together.
