President Trump said Thursday that he “probably” will meet with Russian President Vladimir Putin during a weekend gathering of world leaders in Argentina, but that he still still may cancel the plans over the Ukraine crisis.

Trump intends to have a bilateral meeting with Putin and a handful of other leaders at the G-20 summit in Buenos Aires, the White House said this week, but the potential meeting with Putin comes at a time of heightened political and legal tension relating to a probe of Trump campaign contacts with Russia.
