New York (CNN Business) Twitter suspended an account on Monday afternoon that helped spread a controversial encounter between a Native American elder and a group of high school students wearing Make America Great Again hats.

The account claimed to belong to a California schoolteacher. Its profile photo was not of a schoolteacher, but of a blogger based in Brazil, CNN Business found. Twitter suspended the account soon after CNN Business asked about it.

On Tuesday, a source familiar with Twitter's investigation into the account said the company's initial findings suggest that the account was run from the United States. The source cautioned, however, that determining which country a Twitter account is actually run from can be very difficult.

A legal advisor to Nah Cardoso, the Brazilian social media star whose picture was being used by the account, told CNN that "Cardoso has never authorized any other account to use any type of image or content of her."

The account , with the username @2020fight, was set up in December 2016 and appeared to be the tweets of a woman named Talia living in California. "Teacher & Advocate. Fighting for 2020," its Twitter bio read. Since the beginning of this year, the account had tweeted on average 130 times a day and had more than 40,000 followers.
