US vice president JD Vance suffered an embarrassing blunder earlier this week after being caught poking fun at Donald Trump ahead of his Congress speech.

And after footage subsequently went viral, many viewers have come to an agreement over one aspect of the 40-year-old’s ‘oops’ moment.

For those out of the loop, 78-year-old Trump made his debut presidential speech before an audience of lawmakers yesterday (4 Mar) following a four-year break from the White House.

Ahead of his official address – which would see Trump laying out his key objectives for his upcoming term – however, his Republican VP, JD Vance, was seen having a catch-up with house speaker Mike Johnson.

Waiting at the podium for the father-of-five’s arrival, the duo jointly began poking fun at Trump’s notoriously-lengthy speech-making skills, seemingly not realising that they’d mic’d up.

“By the way, I think the speech is going to be great,” the recording hears Vance say of Trump.

“But I don’t know how you do this for 90 minutes.”

Johnson then replies: “The hardest thing was doing it during Biden.”

The speaker then pushes the microphone down – seemingly only just realising it may have been activated – before adding of Trump’s Democratic predecessor: “When his speech was a stupid campaign speech.”

Even more shocking, is that Vance went on to tell Johnson: “Man, I’ve got to be honest…”

Sadly, however, the VP then leaned in to the speaker’s ear, obscuring the tea he was inevitably about to spill.
