Russian President Vladimir Putin has said that U.S. President Donald Trump had not passed on any secrets to Russian Foreign Minister Sergei Lavrov during a meeting in Washington last week and that he could prove it.

Speaking at a news conference alongside Italian Prime Minister Paolo Gentiloni in the black sea resort of Sochi, Putin quipped that Lavrov was remiss for not passing on what he made clear he believed were non-existent secrets.

Putin said Moscow rated Lavrov’s meeting with trump “Highly,” said Russia was ready to hand a transcript of Trump’s meeting with Lavrov over to U.S. Lawmakers if that would help reassure them.

Complaining about what he said were signs of “Political Schizophrenia” in the United States, Putin said trump was not being allowed to do his job properly.

Two U.S. Officials said on Monday that trump had disclosed highly classified information to Lavrov about a planned ISIS operation.

Russia has repeatedly said that anti-Russian politicians in the United States are using groundless fears of closer ties with Moscow to sabotage any rapprochement and damage Trump in the process.
