Congressman Peter King (R-N.Y.) called the revelation that President Trump's transition team was identified during incidental surveillance activity "extremely significant."

King said the fact that Trump's name appeared in the reports obtained by House Intelligence Committee Chairman Devin Nunes (R-Calif.) was one of a few violations that were committed.

Trump nor his associates were being wiretapped, King said. Instead the surveillance focused on foreign individuals who referenced them.

"Any time your [American's] name comes up, it's supposed to be masked. Reports were written with names of these people and details," King said, adding that the information was then spread around to different entities.

The surveillance could have been for legitimate purposes, King said, but the fact that Trump's and his transition team's names came up is "shameful".

King said Trump "overplayed his hand" by flatly accusing President Obama of wiretapping Trump Tower, but clarified that information pertaining to Trump was used and leaked illegally in the process of conducting other surveillance.

He said authorities must find who gave the order to "unmask" Trump or his associates and who allowed the information to be leaked out.

Nobody inside the Trump Organization was being accused of anything, King said.
