Today is a historic day for the United States.

As well as being number 45, Donald Trump has once again been sworn in as the 47th President of the US, and delivered a powerful address to the nation moments after taking his oath.

Hailing his second presidency as “the golden age of America”, Trump made a number of promises to the American people as he added: “From this day forward, our country will flourish.”

From vowing to take back control of the Panama Canal to promising to rename Mount Denali in Alaska back to Mount McKinley, Trump’s speech was full of defiant declarations.

However, Hilary Clinton – the woman Trump bested in the 2016 presidential election – had a response to one promise that viewers couldn’t ignore.

During his speech, Trump announced that he plans to change the name of the Gulf of Mexico to the Gulf of America — a notion Clinton clearly found very humorous, as she could be seen laughing behind the new President.

And it was a moment X users were quick to comment on.

“Hilary Clinton p***ing her pants laughing when Trump said he will rename the Gulf of Mexico to the Gulf of America,” one X user tweeted.

A second added: “Hillary Clinton laughing at Donald Trump babbling about wanting to rename the Gulf of Mexico to the Gulf of America is every sane person’s response.”

A third wrote: “Hillary Clinton can’t contain her laughter as Trump says he’s changing the name of the Gulf of Mexico to the Gulf of America.”

Elsewhere in his address, President Donald Trump used his inaugural address to outline his vision for America’s future, focusing on national strength, unity, and independence.

“Our power will stop all wars and bring a new spirit of unity to a world that has been angry, violent and totally unpredictable,” Trump declared, emphasizing his belief in America’s ability to lead on the global stage.

Trump projected an image of resilience and determination, assuring the country that it would remain unconquerable.

“We will not be intimidated. We will not be broken, and we will not fail,” he said. “From this day on, the United States of America will be a free, sovereign and independent nation.”
