"Paul has made sanctions relief a cause of his since returning from Moscow last month. During that trip, which he took without any of his colleagues, Paul met with Russian officials and delivered a letter from President Donald Trump to Russian President Vladimir Putin, which the White House later said was written at Paul’s request. In addition to meeting with former Russian President Mikhail Gorbachev, Paul had an hour-long sit-down with Konstantin Kosachev, the chairman of the foreign affairs committee in Russia’s legislature. During that meeting, according to Paul’s office, the senator invited Kosachev, who himself is banned from entering the U.S., to send Russian lawmakers to the U.S. Capitol to meet with their American counterparts. Paul’s amendment would be the first step toward allowing those Russians to travel to the U.S. The Cato Institute, a libertarian think tank, paid for Paul’s trip."
