President Donald Trump just can’t help himself sometimes — not even when it comes to Russia, the country that has dogged his entire presidency.

Amid an impeachment scandal related to his dealings with Ukraine — which the Kremlin invaded in 2014 — Trump dropped a quip Thursday about Russian President Vladimir Putin’s homeland.

He joked in front of television cameras and reporters about building a “Russian Room” in the White House just hours after Speaker Nancy Pelosi told reporters when it comes to Trump “all roads lead to Putin.”

During a lunch in the Cabinet Room with all permanent representatives to the U.N. Security Council, Zhang Jun, China’s ambassador to the United Nations, thanked Trump for a White House tour. He said he was impressed by the executive mansion’s holiday decorations, including in the “China Room.”
