Radio talk show host Mark Levin joined "Fox & Friends Weekend" Sunday to discuss President Donald Trump's allegations of wiretapping of Trump Tower by the Obama administration.

On Thursday, Levin laid out the potential executive overreach of the Obama administration, possible prompting Trump to take to Twitter Saturday morning to make his accusations public.

"This is not about President Trump's tweeting; this is about the Obama administration spying," said Levin, chief of staff for Attorney General Edwin Meese in the Reagan administration.

Levin brought up a report that the Obama administration made two Foreign Intelligence Surveillance Court requests in 2016 to monitor Trump communications and a computer server in Trump Tower focusing on possible links with Russian banks. The first one in June was denied, but the follow-up in October was granted.

"The issue isn't whether the Obama administration spied on the Trump campaign or transition of surrogates; the issue is the extent of it," Levin said.

"Donald Trump is the victim. His campaign is the victim. His transition team is the victim. His surrogates are the victim," he said.

Levin added that former President Barack Obama is likely in some way involved in the alleged wiretapping.

"I will tell you this, he's more involved than he says; it's his executive branch," Levin said.
