WASHINGTON (Reuters) - Senator Mark Warner said on Wednesday that Facebook Inc's move to disable the accounts of a group of New York University researchers who were studying political ads on its platform was "deeply concerning."

Facebook said on Tuesday it had cut off the personal accounts and access of the NYU researchers, who were studying political ads on the site, because of concerns about other users' privacy.
