Trump claims Biden 'doesn't know he's alive' as he slams gaffe-prone president's cognitive abilities

Donald Trump spent a good portion of his Fox News town hall bashing Biden's cognitive state and claiming the President 'doesn't know he's alive'. 

The former President criticized Biden for not being able to 'put two sentences together,' just moments after Trump himself struggled to say a coherent sentence.

During his town hall on Tuesday night - Trump rambled on about gossiping with Ted Kennedy about who the smartest and dumbest people in the Senate at the time were.

According to Trump - he didn't want to reveal who Kennedy said the smartest was because he 'really doesn't like the guy at all'.

The former President claims that in this alleged conversation - which apparently took place at the 'Kennedy Compound' in Palm Beach - Kennedy confided in Trump that Joe Biden was 'probably' the 'dumbest' person in the Senate.

Trump followed his anecdote up with a rant about Biden, saying 'now I see when he's not in prime time for himself... I mean years later he failed on being president when he was... like normal.'

The former President then stuttered on but randomly changed the subject to nuclear bombs, 'something is going wrong and we can't afford it because we have a problem today,' Trump said. 'Nuclear weapons is the single biggest problem the world has.'

'Take Hiroshima or Nagasaki and you look and that was many many decades ago and multiply that times 500. That's what a big bomb would be today,' Trump informed the Fox News town hall audience.

'Whether it's Israel or really major countries,' he stumbled on. 

'Nuclear weapons are the biggest problem we have and we have a man who can't put two sentences together. We have a man who doesn't know he's alive,' Trump claimed. 

Trump's Biden-bashing was accompanied by other extraordinary statements made to the Fox News host Sean Hannity at the Iowa town hall on Tuesday.

The former President refused to rule out abusing power to go after his critics – saying he wouldn't do it 'except for Day One' – when given multiple opportunities to forswear plans for vengeance or a power grab.

Hannity questioned him directly on some of the worst charges from his critics – including that he planned to 'abuse power' or use the justice system to take down his political rivals, and pointing out that some want to call him 'a dictator.'

'To be clear, do you in any way have any plans whatsoever if reelected president to abuse power, to break the law to use the government to go after people,' Hannity asked him.

'You mean like they’re using right now?' Trump responded, without answering the question directly.

'So in the history of our country? What's happened to us again, has never happened before. Over nonsense over nothing made up charges,' Trump said, returning to a refrain about being indicted more times (four) than infamous Chicago mobster Al Capone.

After Trump pivoted to other subjects in the sit-down interview, Hannity came back to the topic, after earlier playing a famous Trump clip telling supporters 'I am your retribution.'

'You are promising America tonight you would never abuse power as retribution?' Hannity asked the former president, who is leading President Joe Biden in a series of polls.

'Except for Day One,' Trump answered.

'Meaning?' Hannity asked him.

'I want to close the border and I want to drill, drill, drill.'

'That's not retribution,' Hannity pointed out.

Then Trump tried to get a laugh out of the line.

'He says: You're not going to be a dictator. I said "no, no, no – other than Day One. We're closing the border. And we're drilling, drilling, drilling. After that I'm not a dictator.'

A Biden-Harris account tweeted out the clip, appending the line, 'Trump: I will be a dictator on day one.'
