Hillary Clinton’s campaign is in turmoil over its use of an image of her campaign staffer being beaten by a protester in a photo that appeared on a campaign website.

In a statement Tuesday night, the campaign blamed the incident on a glitch in the image upload system and said the campaign had removed the image and replaced it with a photo of Clinton.

The campaign added that the campaign “is confident in the integrity of our candidate’s platform and campaign.”

Clinton, the Democratic presidential nominee, is running a tight race in the race for the White House.

She’s facing Republican Donald Trump in the Nov. 8 general election and in a race for Senate in New York that’s expected to go to a runoff between her and Democratic Sen. Kirsten Gillibrand.

In her statement, campaign spokeswoman Amanda Renteria said the photo of the staffer was posted on the campaign website on Nov. 5.

The statement did not say what happened to the image that was used for the campaign’s site.

In addition to the use of the image, the Clinton campaign also released a statement from the campaign chairman John Podesta saying he is “deeply troubled” by the image.

“I can tell you that we are in the midst of a coordinated effort to suppress the vote, which we believe will only harm our candidate, Hillary Clinton,” Podesta said in the statement.
