BEDFORD, N.H. — Donald Trump wondered aloud Thursday whether his Democratic rival, Hillary Clinton, received immunity during an investigation into her use of a private email server while she was secretary of state.

Trump noted that some of Clinton's aides pleaded the Fifth Amendment, and dubbed the group the "FBI Immunity Five."

"They gave so much immunity, there was nobody left to talk to. There was nobody left, except Hillary. They probably gave her immunity, too," Trump said, then asked the crowd whether they agreed. "Do you think Hillary got immunity? ... She got something."

While a handful of Clinton's aides have been given some form of immunity during the FBI investigation, Clinton did not receive any immunity. No charges were filed against Clinton or her aides.

This was one of many attacks Trump made on Clinton and her husband during a Thursday afternoon rally held in an indoor sports complex here in the Granite State. Trump mostly focused on the email controversy and raised questions about the Clinton family's charitable foundation. When someone in the crowd mentioned the attack on Benghazi, Libya, Trump replied: "Well, Benghazi is a horrible thing," before continuing to talk about the email server. A man in the crowd shouted: "Say that at the next debate."

Trump also mocked the crowd sizes that Clinton attracts, including at a rally this week with Sen. Bernie Sanders (I-Vt.), whom Trump accused of having "sold out to the devil." And Trump repeatedly told the crowd to "follow the money" when it comes to Clinton.

"The American people have had it with years and decades of Clinton corruption and scandal. Corruption and scandal," Trump said. "And impeachment for lying. Impeachment for lying. Remember that? Impeach. They're tired of the lies. They're tired of the trivial politics. They're tired of being talked down to, looked down upon and treated like second-class citizens. And they're phenomenal people — you are phenomenal people. The Clintons are the sordid past. We will be the very bright and clean future."

At one point during the rally, Trump mentioned that more than 3,000 people have been shot in Chicago this year. Given that Chicago is the honorary hometown of President Obama, a man in the audience shouted: "Yes we can!"

Trump laughed and said: "Say it again."

"Yes we can!" the man yelled, quoting the president's popular campaign slogan.

"Yes we can," Trump said. "He goes: 'Yes we can.' Oh, boy. That can only happen in New Hampshire, right? Right?"

New Hampshire is the place where Trump had his very first victory at the polls, winning the primary in February and being propelled ahead. With the election six weeks away, local Republicans urged the crowd to vote via absentee ballot and to encourage their friends and neighbors to do the same.

For months, Clinton has held a lead over Trump in New Hampshire polls.

“You know, this is where I had my first victory. We do know that, right?” Trump said. "... This is where it all started."
