Politician denies sending tweet as giant video wall shows … the tweet

Giant video walls are becoming a fixture on TV news sets around the globe — and a British show used its to catch a politician in a lie.

Sophy Ridge, host of Sky News‘ “Sophy Ridge On Sunday” was interviewing U.K. international trade secretary Liam Fox and brought up a controversial tweet he sent.

When Fox denied sending the missive, Ridge gestured to it on the wall — though Fox didn’t seem to notice.

He then continued by saying “… it was taken from a speech I gave a year and a half ago and it was tweeted out by, I think, the Guardian and it was an incomplete reference in any case.”

The whole time the tweet remained on the video wall on the network’s “glass box studio” behind him.
