The FBI applied a different standard of justice to Hillary Clinton in 2015 than it did for Donald Trump in 2016, Sen. Lindsey Graham, R-S.C., charged Sunday.

In an interview on Fox News’ “Sunday Morning Futures,” Graham said newly declassified documents unveil the disparity.

“In March of 2015 the FBI finds out about a plot by a foreign government to lobby the [Hillary Clinton] campaign and funnel millions of dollars into the Clinton campaign illegally,” he explained.

“They open up an investigation, they want a FISA warrant against a Clinton operative connected to the foreign government. What happens? The FBI’s [leadership] says ‘we’re not going to let you get a warrant until you brief the Clinton campaign’ and in October of 2015, FBI personnel met with the Clinton campaign to tell her about the problem so she could fix it and they never issued the FISA warrant.

“That was the right way to do business.”

But in 2016, it was a different story, Graham said.

“Four counter intelligence investigations opened by the FBI against the Trump campaign” in 2016, he said. “They never tell him about it so he can fix it… They never told Trump ‘oh, by the way, you’ve got a Carter Page problem, you’ve got a George Papadopoulos problem.’ As a matter of fact not only did they not tell Trump, they used a generic briefing to spy on Trump.”

Graham acknowledged foreign governments are going to try to influence U.S. elections “for the rest of our lives.”

“We need to have tools to find out about that and when you find out about a foreign government trying to influence a campaign, you need to protect the campaign, not spy on it.”

“They did it right for Clinton, they used the counter intelligence investigation to spy on Trump. That is a double standard. That is political bias…. I cannot tell you how inappropriate it is to do what they did to Trump. They never told him about the problem, they used the problem as a way to spy on him.”
