Alexandria Ocasio-Cortez compared Trump to a parasite on Late Night with Seth Meyers last night.

The democratic socialist joked that President Trump was a 'nematode' near the end of the interview while revealing her love for biology.

Ocasio-Cortez said: 'Science was my first passion. I studied microbiology and the impacts of antioxidants on a model organism known as the C. elegan, which is of the nematode family.'

Meyers then joked that she shared that passion with President Trump. 'I think he did that too,' he said.

But before Meyers could finish, Ocasio-Cortez interrupted, 'Because he's a nematode?' she joked, as the crowd burst out laughing.

Nematodes are microscopic worms that act as parasites in animals and plants. They eject bacteria inside the animal's body, which then multiplies and causes blood poisoning, leading to death.

Ocasio-Cortez has consistently swiped at the president well before becoming a House Representative in January.

The democratic socialist said there was 'no question' Trump was a racist earlier this year

She said earlier this year there was 'no question' Trump is a racist. In an interview with CBS News, she based her claim on 'words that he uses, which are historic dog whistles of white supremacy'.

Last week, the Democratic Rep. was awarded 'three Pinocchios' from a fact-checker for her claim that he transferred no money to fight opioid addiction after he declared a national health emergency.

Ocasio-Cortez retweeted a C-SPAN clip of her questioning the White House's director of drug policy James Carroll with her claim: 'Amount President Trump has transferred from other agencies to fund his 'Build the Wall' Emergency: $10s of millions, & has identified billions more. Amount he's transferred to address the Opioid National Emergency: $0.'

But The Washington Post's Fact Checker blog found the freshman lawmaker from New York was making a 'highly misleading comparison' and took issue with her attempt to connect the president's actions in the opioid crisis with his actions in trying to build his border wall.
