WATCH: Did Donald Trump slur his words during this speech?

As US President Donald Trump addressed the nation, making the historic declaration that Jerusalem would be recognised as the capital of Israel, it was his seemingly slurred speech that stole the spotlight.

Toward the end of the speech, social media users quickly pointed out his usual speech pattern and above average amount of sniffling.

Among a series of stifled words, Trump noticeably mispronounced “states,” when concluding an address to the nation, sparking rumours of health problems for the 71-year-old president.

It also created further speculation that the president wears false teeth.

"There is clearly some abnormalities of his speech,” CNN's Chief Medical Correspondent, Dr. Sanjay Gupta said.

"You could call it slurring or just a little bit of difficulty forming the words."

The White House promptly shut down growing speculation, saying the president’s throat was merely dry during Wednesday’s address.

“His throat was dry. There's nothing to it,” White House spokesman Raj Shah told reporters. “I’m saying there’s nothing to it.”

It’s not the first time that Trump has had difficulty speaking during a couple of recent addresses.

During a televised speech summarising his trip to Asia last month, Trump appeared to have trouble breathing and stopped to drink from a bottle with two hands.
