WASHINGTON — The last time President Trump met in the Oval Office with Sergey V. Lavrov, the Russian foreign minister, it did not go so well.

Mr. Trump had just fired James B. Comey, the F.B.I. director, and exulted about the move to Russia’s top diplomat. Then he told Mr. Lavrov and Sergey I. Kislyak, who then was finishing a tour as Russia’s ambassador to Washington, about the penetration of an Islamic State group working to make explosives that fooled airport X-ray machines by looking like batteries for laptop computers. That disclosure blew an important intelligence source for Israel, which had kept its operation to get inside ISIS a secret — and was outraged by Mr. Trump’s indiscretion.

Now, at the very moment the maelstrom around the Trump campaign’s contacts with Russians in the 2016 election is being revisited by the inspector general of the Justice Department, Mr. Lavrov is back. The Kremlin said its foreign minister has plans to meet with Mr. Trump on Tuesday in addition to talks with Secretary of State Mike Pompeo.

Late Monday, the White House confirmed an Oval Office meeting between Mr. Trump and Mr. Lavrov for Tuesday afternoon. Considerable evidence suggests any conversation with Mr. Lavrov would include the last major nuclear arms control treaty still in force between the United States and Russia: the Obama-era New START treaty, which in recent days President Vladimir V. Putin of Russia has said he wants to extend for another five years.
