On Saturday, Sean Hannity, host of Fox News' "Hannity" and nationally syndicated radio show "The Sean Hannity Show," vanished for a few hours.

After Hannity posted a mysterious tweet saying "Form Submission 1649," a tweet which has since been taken down, a "Sorry, that page doesn't exist" error message came up for anyone who tried to visit his Twitter page. According to the Associated Press, Twitter confirmed to Fox News that Hannity's account had been compromised.

"While we normally do not discuss individual accounts, for privacy and security reasons, we have permission from the account owner to confirm that account was briefly compromised," Twitter said by email.

There have been many theories as to why Hannity's account disappeared, many of which have been conspiracy theories blaming the "deep state," due to Hannity's major support of President Donald Trump.

After the debacle, Hannity tweeted his thanks to his supporters throughout the time Hannity's account was compromised and promised to keep working on investigating the deep state.

As of now, it is still unclear what caused Hannity's account to disappear.
