President Trump tweeted Tuesday morning against a report that he shared classified intelligence information with Russian officials last week, saying he has “an absolute right” to share facts pertaining to terrorism and airline safety.

“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,” Mr. Trumptweeted.

The Washington Post report claimed that Mr. Trump shared this information in a meeting with Russian Foreign Minister Sergey Lavrov. The report claims the information came from a U.S. partner regarding the Islamic State terror group.

The report cites sources familiar with what was said in the meeting, prompting Mr. Trump to also address his concerns with “leaks” from the intelligence community.

“I have been asking Director Comey & others, from the beginning of my administration, to find the LEAKERS in the intelligence community…..,” the president tweeted.

Secretary of State Rex W. Tillerson and National Security Adviser H.R. McMaster have both pushed back on the report, saying Mr. Trump had a conversation with the Mr. Lavrov on counterterrorism efforts, but he did not reveal any “sources, methods or military operations.” Mr. McMaster went even further, calling the report “false” in a statement Monday evening.
