"Right now, we are focused on the next five weeks of winning the Democratic nomination. If that does not happen, we are going to fight as hard as we can on the floor of the Democratic convention to make sure that we have a progressive platform that the American people will support," Sanders said during an interview with CNN's Wolf Blitzer broadcast on "The Situation Room."
"Then, after that, certainly Secretary Clinton and I can sit down and talk and see where we go from there." 
Asked if Sanders would drop out of the race if he were offered the VP slot now, the independent Vermont senator responded, "I think that that is a hypothetical that will not happen."
Clinton has all but clinched the Democratic nomination but she has shied away from directly calling for her opponent to drop out of the race.
Sanders has insisted that he'll fight until the party's convention in July, hoping to play a role in crafting a more progressive party platform.
"We're going to be in this until the last ballot is cast," Sanders reiterated Friday.
"Hillary Clinton and I disagree on many issues, I think her judgement on the war in Iraq was bad, I think her judgement on trade policies where she supported virtually every one of these disastrous trade policies was bad, I think the fact that she supports a $12 minimum wage when clearly we need a $15 an minimum wage, I think that's bad. I think her creating super-PACs and raising money from Wall Street and other powerful special interests, not a great idea," Sanders said.
Trump has invoked some of Sanders's criticism of Clinton's "bad judgement" to attack the former secretary of State amid his pivot toward the general election. Sanders accused Trump of trying to sow division within the Democratic party but didn't back away from his claims.

"Yes, that's right, of course she had bad judgement. She voted for the war in Iraq. that's bad judgement," Sanders said Friday.
