Michelle Obama proves Stevie Wonder really is her favorite

At the memorial for Dallas police officers held at the Meyerson on Dallas Police Chief David Brown recited a Stevie Wonder song to hundreds of his police officers who were in the audience.
President Barack Obama, who followed Brown, quipped, “I’m glad I met Michelle first, because she loves Stevie Wonder.”
When Michelle Obama appeared on The Late Late Show’s carpool karaoke, she proved the president was right when she and James Cordon began with Stevie Wonder’s “Signed Sealed Delivered.”
“I know every Stevie song on the planet,” Obama tells Cordon.
Here’s the video that also features the Obama cover of “Single Ladies” and Missy Elliott joining to sing “This Is For My Girls.”
