WATCH: Trump took a hilarious jab at Jim Acosta when he saw him in the White House

The strained relationship between President Donald Trump and the media took another downward turn when the president threw a humorous jab at CNN's Jim Acosta, one of his more vociferous critics.

Trump had just taken questions from the media from the Oval Office when he saw CNN's chief White House correspondent and decided to mock one of the tweets Acosta had sent to undermine the president.

"Good job yesterday, I appreciate your sales pitch," said the president.

"I didn't see any danger on the border Mr. President," responded Acosta.

"That's because we had a wall," Trump fired back.

The president was referring to a tweet Acosta had posted of himself near the border barrier in McAllen, Texas, ostensibly posted to show that there wasn't an immediate crisis demanding a wall.

"I found some steel slats down on the border," Acosta tweeted.

"But I don't see anything resembling a national emergency situation," he added, "at least not in the McAllen TX area of the border where Trump will be today."

Many noted that his intent backfired because the presence of a border barrier had created the tranquillity Acosta noted.

Trump took up the same argument when he jabbed at Acosta. The interaction was caught on video, but the sound is somewhat drowned out by other reporters and photographers.
