Ellen DeGeneres is responding to accusations of racism she’s received since posting an edited photo of herself and Usain Bolt to her Twitter account.

“I am highly aware of the racism that exists in our country,” DeGeneres wrote on Tuesday. “It is the furthest thing from who I am.”

The image that sparked the controversy depicts DeGeneres on the back of the Jamaican sprinter as he finished first in the men’s 100m event at the Rio Olympics on Sunday. “This is how I’m running errands from now on,” DeGeneres captioned the photo.

The original photograph, which shows Bolt looking back and smiling as he is well ahead of his competitors in the semifinals, went viral following the race.
