The Twitter account of Fox News host and staunch Donald Trump ally, Sean Hannity, appears to have been deactivated for a number of hours before being restored.

The account, which has nearly three million followers, disappeared last night after posting a strange tweet saying "Form Submission 1649 | #Hannity".

When people attempted to search for the account they were then presented with a page that read: “Sorry, that page does not exist”.

The verified account re-appeared this morning, initially with only a few followers, before having its full following restored.

Twitter is yet to comment on reason for the account's disappearance.
