House Freedom Caucus Chairman Mark MeadowsMark MeadowsJan. 6 committee chair says panel will issue a 'good number' of additional subpoenas Graham told Trump he 'f'd up' his presidency: book Executive privilege fight poses hurdles for Trump MORE (R-N.C.) said on Wednesday it is very likely that undercover FBI sources taped members of the Trump campaign.
"There's a strong suggestion that confidential human sources actually taped members within the Trump campaign," Meadows told Hill.TV's Krystal Ball and Ned Ryun on "Rising."
"There is strong suggestions in that, with some of the text messages, emails, and so forth who was involved, that extraordinary measures were used to surveil," he continued.
Various House Republicans, including Meadows, have pushed for the declassification of portions of a surveillance application that helped the FBI monitor former Trump campaign adviser Carter Page.
The documents also include "all text messages relating to the Russia investigation" from former FBI Director James Comey and other top federal officials.
Some House Republicans have argued that the Foreign Intelligence Surveillance Act warrant for Page was wrongly obtained because it pulled information from the unverified dossier on Trump compiled by former British intelligence officer Christopher Steele during the 2016 campaign.
"Now whether that was a confidential human source taping an individual, that's what I believe it is, but it's important that we look at this because the whole narrative of 'spygate' and tapping and all of that have been narratives that are out there but unproven," he said.
"There was a suggestion that there was as many as five different people that perhaps came under the surveillance of the [Department of Justice] and FBI in the early days of the Trump transition and campaign, and I think that we need to get answers to that," Meadows said.
Trump directed the classified documents to be released last month, but later delayed the release of the documents, saying "key allies" expressed concerns of the declassification.
