Russian Federation has vetoed a UN Security Council resolution demanding a swift investigation into the attack.
Trump had previously questioned NATO's relevance.
The meeting and press conference mark an important opportunity for the president, as it they will him a chance to reorient himself to the alliance that he called "obsolete" during the 2016 campaign.
Trump said it's "possible" but "unlikely" Russian Federation did not know Assad's team was prepping that gas attack on Syrian citizens.
When asked about whether his opinion on Russian Federation leader Vladimir Putin has changed, Trump responded "We're going to see about that".
Washington responded to the suspected chemical attack by targeting a Syrian air based with a barrage of cruise missiles in an operation that incensed Moscow.

President Donald Trump is saying he may reshuffle some of his major domestic priorities. He also gave credit to Trump for bringing the issue into focus. "It's very bad for this world", Trump told Fox Business News. That's despite an ongoing impasse between GOP hardliners and moderates.

"Putin is backing a person that's truly an evil person", the president said this week in an interview with the Fox Business Network.
Trump says China's long history with North Korea complicates China's ability to crack down on the North's nuclear program. Such collaboration, he said, could help the two sides later address "more serious problems". "I think it's wonderful that they abstained", he said.
