SAN FRANCISCO -- Twitter is bringing back special labels to help users identify accounts and tweets from U.S. political candidates.
Twitter hopes its efforts will help people know when candidates are behind the words attributed to them. This could prevent someone from creating an account pretending to be a politician, for instance, or attributing a tweet to a candidate who didn't actually make the tweet.
Facebook also verifies accounts for public figures and celebrities, while YouTube verifies official channels. But they don't go as far as adding election labels.
Labels will be used only for general election candidates and will start appearing once candidates have won their parties' primaries or have otherwise qualified for the general election ballot.
Major presidential candidates already have blue check marks to indicate that Twitter has confirmed the accounts are legitimate. Many candidates for House, Senate and gubernatorial races have them as well.
Twitter said Thursday it will verify additional accounts, even if candidates do not seek them, by working with the nonprofit, nonpartisan Ballotpedia. Twitter said the verifications will happen on a rolling basis as candidates qualify for next year's primaries.
