The Federal Bureau of Investigation is leading an inquiry into the Twitter hacking, according to sources familiar with the situation, as more Washington lawmakers raised alarms about the breach of high-profile accounts on the social media platform.
Earlier the law enforcement agency had said hackers appeared to commit cryptocurrency fraud after they seized control of the Twitter accounts of celebrities and political figures including Joe Biden, Kim Kardashian, Barack Obama and Elon Musk.
The FBI did not immediately respond to a question about it leading an inquiry into Twitter.
A day after the breach, it was not clear if the hackers were able to see private messages sent by the account holders. U.S. lawmakers worried about future attacks.
“While this scheme appears financially motivated…imagine if these bad actors had a different intent to use powerful voices to spread disinformation to potentially interfere with our elections, disrupt the stock market, or upset our international relations,” U.S. Senator Ed Markey, a Democrat, said in a statement.
