Transcript for Russian propaganda machine responds to US missile strike

this will end hopes of a warmer relationship with Vladimir Putin. And the warning for the United States, a message aimed at president trump. Russian officials calling what they saw last night, a clear act of aggression. Testing what Jon just pointed out, hope for a better relationship with Vladimir Putin. Here's Brian Ross. Reporter: The Russian propaganda machine is working overtime tonight. Russian TV outlets quickly distributed this footage of what it called the failed U.S. Attack. A reporter inside a fortified hangar, damaged but still standing. Five jet fighters seemingly untouched. And the runway with no apparent damage, where the jets took off. And the Russian prime minister taking to Facebook to say his country's high hopes for Donald Trump had been smashed, that it took only two and a half months for "Trump's election promises" to be broken "By the existing power machine." Look, hey, Putin likes me. Reporter: It wasn't that long ago that candidate Donald Trump had nothing but praise for Russia and Vladimir Putin. I think I'd get along with him. I respect Putin. He's a strong leader. Reporter: But now the trump love affair with Russia seems to be over, at least based on the words today of his ambassador to the united nations who called Russia either complicit, incompetent or -- It could be that the Assad regime is playing the Russians for fools. Reporter: In response, Russia and Syria said the U.S. Attack only helped ISIS and other terrorists who are fighting against the Assad regime in Syria. It makes the United States of America a partner of ISIL, jabra Al nusra and other terrorist groups. Reporter: But the U.S. Says there is no doubt of the role of Syria in the horrific chemical attack. Brian, we know officials revealed on the same day of the attack, a hospital treating victims was hit by a second bomb attack, a more conventional bomb, in this case. Was it the Russians? That's the question. You see the video from inside the hospital, the bomb went off. The Pentagon knows it was a Russian jet, they don't know who was piloting it, but they can't rule out that it was a Russian pilot. And two more jets took off from that airfield today. Thank you. We move on to the other major story developing at this hour.
