US President Donald Trump considered that he had right to share information with Russia.

“As President I wanted to share with Russia (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining to terrorism and airline flight safety. Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism,” Trump tweeted.

Several U.S. news organizations reported that the president, in the Oval Office meeting with Russian Foreign Minister Sergey Lavrov and Ambassador Sergey Kislyak, disclosed information considered highly classified.
