Stock futures moved higher on Tuesday as crude oil continued to climb, though another controversy from the Trump camp kept markets on edge. 

S&P 500 futures were up 0.18%, Dow Jones Industrial Average futures added 0.22%, and Nasdaq futures were up 0.22%.

Crude oil edged higher on Tuesday, solidifying big gains achieved a day earlier. Oil prices surged on Monday, reversing big dips seen last week and putting commodities at two-week highs, after energy ministers from Russia and Saudi Arabia surprised markets by calling for an extension to an oil production cap agreement.

An extension to the OPEC deal will be the main point of conversation when the 13 member countries meet in Vienna on May 25. The current agreement, established last November, is set to expire at the end of June.

The oil market has already reached a balance and the correction to a global supply glut will continue in the near term, the International Energy Agency said in its monthly report on Tuesday. The IEA held its demand growth forecast at 1.3 million barrels per day in 2017. 

West Texas Intermediate crude was up 0.9% to $49.27 a barrel on Tuesday morning. 

Donald Trump divulged highly classified intelligence to Russia during a meeting last month, according to a shocking report from The Washington Post. Trump reportedly shared top-secret information on the fight against ISIS with Russian Foreign Minister Sergei Lavrov and Russian Ambassador Sergei Kislyak in a meeting in which U.S. media was barred. The meeting raised eyebrows just a day after Trump fired FBI Director James Comey, who was head of an investigation into Trump and his campaign's alleged ties with Russia.
