National security adviser H.R. McMaster spoke with his British counterpart on Thursday about press secretary Sean Spicer's comment from the White House podium about a Fox News report that said British intelligence helped wiretap Trump Tower during the 2016 campaign, a White House official said Friday.
The official described the conversation as "cordial" where McMaster described Spicer's comment as "unintentional."
McMaster also told his counterpart that "their concerns were understood and heard and it would be relayed to the White House."
Earlier Friday, a spokesman for May said senior UK officials had protested to the Trump administration after the claims were repeated by Spicer.
"We've made clear to the US administration that these claims are ridiculous and should be ignored. We've received assurances that these allegations won't be repeated," May's spokesman said, CNN reported.
