No Ukraine for McCain: US constitution precludes senator from joining reform council ― RT News

US Senator John McCain says he won’t be joining Ukraine’s International Advisory Council as the US constitution forbids it. The board, headed by Georgia’s fugitive ex-leader Mikhail Saakashvili, was created on President Poroshenko’s order.

“I was honored to be asked to join Ukraine's International Advisory Council on Reforms, a forum for discussing ways to ensure Ukraine’s territorial integrity and security and support the country’s democratic future in the face of Russian aggression. However, under provisions of the US Constitution concerning the interaction of Members of Congress with foreign governments, I am obligated to decline the invitation,” McCain said in a statement on his website.
