Russian President Vladimir Putin has lashed out at U.S. politicians whipping up what he described as “anti-Russian sentiment” for being either “stupid” or “dangerous,”  and dismissed the ongoing scandal around President Donald Trump sharing classified intelligence with Russian officials as “political schizophrenia.”

Speaking at a joint news conference with the visiting Italian prime minister, Putin said on Wednesday Moscow initially found debates about Russia’s meddling in U.S. politics as “funny” but said Moscow is now “concerned because it’s hard to imagine what the people who produce such nonsense can come up with next.”

Putin dismissed the U.S. politicians, whom he did not identify, as either being “stupid” or “dangerous and unscrupulous” who are wittingly “causing the damage to their own country.”

Trump came under fire earlier this week after it was revealed that he shared the sensitive intelligence with Russian Foreign Minister Sergey Lavrov and Russian ambassador to the U.S. Sergei Kislyak.

Putin even suggested that Russia share the records of last week’s talks between Trump and Lavrov with the U.S. Congress, if the White House approved.

Putin joked that that he would reprimand Lavrov because “he hasn’t shared those secrets with us.”

Asked what he thinks of Trump presidency, Putin said it’s up to the American people to judge but his performance can only be rated “only when he’s allowed to work at full capacity,” implying that someone is hampering Trump’s efforts.
