Special counsel Robert Mueller’s investigation into Russian interference in the 2016 election has gone global, according to a Thursday morning report from the Daily Beast.

Court documents that Mueller plans to file in 2019 will highlight the special counsel’s expanded probe into Middle Eastern countries’ efforts to influence American politics, according to three sources familiar with the new development who spoke to the Daily Beast.
