US government wiretapped former Trump campaign chairman Paul Manafort

US investigators wiretapped former Trump campaign chairman Paul Manafort under secret court orders before and after the election, apparently, an extraordinary step involving a high-ranking campaign official now at the center of the Russia meddling probe. The government snooping continued into early 2017, including a period when Manafort was known to talk to President Donald Trump. Some of the intelligence collected includes communications that sparked concerns among investigators that Manafort had encouraged the Russians to help with the campaign, according to three sources familiar with the investigation. Two of these sources, however, cautioned that the evidence is not conclusive. Special counsel Robert Mueller's team, which is leading the investigation into Russia's involvement in the election, has been provided details of these communications.
