WASHINGTON — Hillary Clinton’s campaign is calling on the FBI to make public all the materials it delivered to Congress about her private email server.

“Anything that the FBI gives to Congress they should give to the public,” Clinton running mate Sen. Tim Kaine told NBC’s “Today” show on Wednesday.

On Tuesday, Congress received the FBI’s investigation summary into Clinton’s email server and notes from a 3½-hour interview with the former secretary of state.

Congressional Republicans are looking into why the FBI declined to press charges against the Democratic presidential nominee.

A leading Clinton critic, Sen. Charles Grassley, said much of the material sent to Congress is unclassified, while the sensitive material is concentrated around classified emails.

He also urged public release.

“The public’s business ought to be public, with few exceptions. The people’s interest would be served in seeing the documents that are unclassified,” said Grassley (R-Iowa).

Team Clinton wants everything made public at one time to prevent a slow drip of selective, politically motivated leaks.

“What we’ve seen is this lengthy multimillion-dollar congressional investigation that has been highly partisan where they wanted to leak out this or that to try to make their case against Hillary Clinton,” Kaine said. “Let the public see what the FBI decides to let Congress see.”

Congressional Democrats are miffed that the FBI set a new precedent by handing over its investigative notes to a closed case.

Rep. Adam Schiff (D-Calif.) called the decision to turn over case notes “unjustified and unwise.” Making public witness statements could deter others’ “willingness to cooperate in the future” and also “opens a Pandora’s box of requests from Congress” on other closed cases, such as a banking committee demanding notes on Wall Street executives who weren’t charged in the financial meltdown, he said.

“That concerns me greatly,” Schiff told MSNBC’s “Morning Joe” Wednesday.
