Robert Mueller looks into Trump's cozy relationship with the United Arab Emirates

Special Counsel Robert Mueller has subpoenaed an unnamed witness, and is seeking all communications with President Trump and nearly a dozen of his closest advisers. The grand jury subpoena asks for texts, phone logs, notes and work documents dating back to a few months after Trump announced his run. Mueller’s investigation also appears to be widening in scope. He’s reportedly looking into whether the United Arab Emirates tried to buy influence with the Trump campaign.
