Biden also blasted Trump for his action on Friday morning when he tweeted around 3a.m slandering the media and blasting former Miss Universe Alicia Machado for being used as a tool by Hillary Clinton in her presidential campaign.
In a video chat with CNN on Tuesday, Biden said: "He's not a bad man,"
"But his ignorance is so profound, so profound."
"I bet he couldn't carry his bag 18 holes in one of his own golf courses, speaking of energy," Biden said.
"Can you imagine the President getting up at 3:30 in the morning and tweeting vitriol?"
"Since when does somebody who lives at the top in the world, in a penthouse overlooking the world, be in a position that he doesn't feel any obligation at all to pay any federal income tax to support the military, to support education, to support our foreign policy?" Biden said about Trump.
"Since when is that a patriotic thing to do? Can you imagine any other president, any other president, just ever say that and be proud of that? I can't fathom it."
Biden also said that despite Trump's promises to challenge the status quo by becoming president, his proposed tax plan will preserve the tax breaks he took advantage of.
"What he's proposing in the tax cut would lock in all of those special interests from real estate folks and cut their taxes even more," Biden said. "This is all about Trump. This is all about Trump."
Biden continued: "What's that say about all the people here? Are they all suckers for paying their taxes, because they can't hire a tax lawyer, because they couldn't make significant contributions to try to change the law to benefit themselves? Come on, man. That's just not right."
The U.S vice president also said he'll invite Trump to the "battlefield" with him in Afghanistan and Iraq so that Trump could experience what soldiers go through after Trump said on Monday that Army veterans suffer from PTSD and 'are weak'.
"I was asked to present a Silver Star to a young man who had jumped into a burning Humvee to pull out his buddy after an IED exploded," Biden said. "And the kid died. The commanding general ... asked me to pin on a Silver Star, when I was there. You know what the kid said to me? 'I don't want it. I don't want it. He did not live, sir. He did not live, sir.' That kid probably goes to sleep every night with a nightmare."
"How can (Trump) be so out of touch and ask to lead this country?" Biden asked.
