Republican U.S. Rep. Marsha Blackburn's online video announcing her campaign for U.S. Senate has been blocked in any Twitter advertisements after the social media company objected to a line that refers to the lawmaker stopping the "sale of baby body parts."

Blackburn's campaign announced Twitter's decision on Monday after a representative from Twitter informed her campaign that the line "had been deemed an inflammatory statement that is likely to evoke a strong negative reaction." The language violates Twitter's policy for advertisements, the company said.

"If this is omitted from the video it will be permitted to serve," a Twitter representative said in an email to a political ad agency working for the campaign.

Although Twitter blocked the video as an online ad, Blackburn is allowed to share it on her campaign Twitter account.
