President Donald Trump unveiled a plethora of political promises and claims during his no-holds barred rally in Orlando, Florida on Tuesday announcing his 2020 re-election bid. 

During his speech, Trump claimed he'd cure cancer and AIDS -- but only if he’s elected to a second term.

"We will eradicate AIDS in America once and for all -- and we are really close," boasted Trump at his rally, which some blasted as neo-fascist.

In front of some 20,000 of his supporters packed into the Amway Center, Trump said he’ll also work to cure cancer.

While short on specifics as to how he’d get these twin jobs done, Trump upped the ante and insisted he’d also "come up with the cures" to other devastating diseases.

"We will push onward with new medical frontiers," said Trump. "We will come up with the cures to many, many problems, to many, many diseases including cancer and others. And we're getting closer all the time."

Trump told his base he has done something in the fight against HIV and AIDS. In his State of the Union address earlier this year, he promised to eradicate AIDS by 2030. His critics state Trump has done nothing to advance this agenda.

Instead, they point to the fact Trump’s budget proposal will divert money away from HIV/AIDS research to fund detention centers for undocumented immigrant children.

More recently, the Trump administration requested $291 million for the first phase of an initiative to reduce new HIV infections in the U.S. in its 2020 budget proposal. The budget also calls for an increase in funding for the Ryan White HIV/AIDS Program. It also wants money to pay for healthcare services and support, and another $50 million to expand access to the anti-HIV drug regimen known as PrEP.

Trump’s proposal to cure cancer comes two years after a similar promise was made by former vice-president Joe Biden in October 2015. Biden is now the frontrunner among Democrats as the party’s presidential nominee for 2020.

Beau Biden, Joe's elder son from his first marriage, was only 46 years old when he died from brain cancer on Jan. 6, 2015.

After Beau’s death, his grieving father delivered a speech at the Rose Garden in October 2015 promising a "moonshot" to cure cancer. Joe Biden’s remark led to the original Cancer MoonShot 2020 initiative.

Last week, Biden reiterated his promise to find a cure for cancer.

"I promise you, if I'm elected president, you're going to see the single most important thing that changes America -- we're going to cure cancer,” said Biden at a Democrat campaign rally in Ottumwa, Ohio.

Biden’s remarks drew instant scorn from Trump’s eldest son Donald, Jr. who scoffed, "Wow, why the hell didn't you do that over the last 50 years, Joe?"
