Twitter is expanding its requirements for political advertisers in the US. 

The policy, announced Thursday, now extends to any political candidate in the US, not just federal candidates. That means, for example, that ads for the campaigns of dozens of gubernatorial candidates running this November must come from advertisers in the US, with their location certified by Twitter.
