House Minority Speaker and senior Democrat Nancy Pelosi said she received "obscene and sick" calls
Twitter has reinstated a suspended account that publicised leaked personal data belonging to Democrat politicians.
On Friday, the hacker known as "Guccifer 2.0" released contact details of 193 current and ex-Congress members.
House Minority Leader Nancy Pelosi later told colleagues she had received "obscene and sick calls" after her phone number was leaked.
Twitter declined to comment on the reasons for the suspension and subsequent reinstatement.
Wordpress also blocked some content on Guccifer's blog which has not been reinstated.
