Asked about the claim, Wallace stated the UK's traditional response of not confirming or denying questions of intelligence before suggesting the claim was wrong and that their intelligence officials had more pressing matters.
"I don't think our intelligence services have any spare capacity to spend time spying on our friends and allies," Wallace said. "You know, if you want to know what's going on in American politics, switch on the news, go to a press conference, and you can find out what's going on."
Trump has repeated a version of the original claim on social media since the 2017 back-and-forth, including in a tweet this past April.
Pressed in his CNN interview on Tuesday, Wallace declined to "speculate on intelligence matters" before again downplaying the spying claim.
"In the days of social media, there's an awful lot of speculation that goes on about these things," Wallace said. "There is no big conspiracy, and the idea that I would take an intelligence officer off a job of, I don't know, targeting al Qaeda in a place that's of mutual (interest) to us, to put him on spying of a campaign, of a presidential candidate, I think it's just not -- it's not going to be the reality."
