Donald Trump begged federal lawmakers on Wednesday to act swiftly to determine whether Hillary Clinton perjured herself during a congressional testimony about her emails and convince the FBI and Justice Department to launch a public corruption probe into her charitable foundation.

"It's impossible to tell where the Clinton Foundation ends and the State Department begins," the Republican presidential nominee said to an audience chanting "lock her up" during his campaign rally in Tampa, Fla.

Trump claimed Clinton "lied to Congress," but said he was unsure "if Congress is going to do anything about it."

"I'm so sick of looking and seeing and I hear reports [about] Congress — they don't do anything," he claimed.

He continued, "Congress ought to act. [Clinton] lied to Congress 100 percent. Everybody agrees and they take so long to act. By the time they act, you're going to say 'What was it?' You won't even remember what happened."

"Let Congress act today," Trump said. "Let Congress act immediately."

Trump's demand for congressional action against Clinton comes as the House Judiciary Committee plans to probe FBI officials next month over how the testimony Clinton gave to Congress about her emails practices last year compares to what she told investigators over Fourth of July weekend.

The FBI delivered a package of documents related to its investigation into Clinton's personal email server to Republican lawmakers last Tuesday.

"Hillary Clinton is out there saying there's not very much sensitive information in there, that she didn't trade in sensitive classified information. It's so sensitive and so classified that even I as the chairman of the Oversight Committee don't have the high level of clearance to see what's in those materials," Rep. Jason Chaffetz, R-Utah, said of the documents earlier this week.
