Donald Trump has claimed the US will cure AIDS and childhood cancer “very shortly".
Addressing a crowd at an Ohio rally last night, the US president said: “The things we’re doing in our country today, there’s never been anything like it.
“We will be ending the AIDS epidemic shortly in America and curing childhood cancer very shortly.”
But his claims were met with skepticism.
Louisiana Democrat Rob Anderson accused the president of lying.
He wrote on Twitter: "Trump lying about campaign promises: 'Mexico will pay for the Wall!', 'We will cure AIDS and childhood cancer!', 'I’ll release my tax returns'. 'Louisiana will get a new I-10 bridge!' ... but only AFTER you elect him again. Seems legit."
Meanwhile, political commentator Josh Dawsey said the promise was "optimistic".
The rally was part of Trump's 2020 election campaign, in which the Republican hopes to win a second term in the White House.
Tweeting videos from the event, Trump used the hash tag #KAG2020, referring to the campaign slogan “Keep America Great” after 2016’s “Make America Great Again".
He branded his party as the party of “freedom” and the “American Dream” while labelling the Democrats as the party of “high taxes, high crime, open borders and late-term abortion".
Trump's boast was similar to one he made at a rally in June this year.
He claimed the country, under his government, would cure "many diseases - including cancer", as well as promising to "eradicate AIDS" in America.
