front and in the actions that they take. but would not specifically say as president biden did that the project would not move forward if russia were invade ukraine. now biden also warned that he believes that vladimir putin is ready toin. but that he simply doesn't flow if they are planning on doing so and he offered a piece of advice for american citizens that are currently in ukraine. take a listen. >> i don't know that he knows what he's going to do. and i think he has to realize that it would be a gigantic mistake for him to move on ukrainian, the impact on europe and the rest of the world would be devastating. a and he would pay a heavy price. i think it would be wise to leave the country. i don't mean -- i'm not talking about our diplomatic core, i'm talking about americans who are there. i hate to see them get cross in a cross fire if they did and there is no need for that and i were they, i would say leave.
