The furor over the FBI probe of Hillary Clinton’s emails is helping Donald Trump among independent voters in key swing states.

In Wisconsin, a state that for months has been seen as safe Democratic turf, a new Marquette Law School poll released Wednesday found a shift in independent voters’ views. Many moved toward Trump after the FBI said Friday it was again probing Clinton’s use of a private email system for government business.

In Florida, a new CNN/ORC survey of Florida voters had Clinton up 2 and Quinnipiac had her up 1. Trump was leading among independent voters, 46-40, Quinnipiac found.

In Pennsylvania, Quinnipiac gave Clinton a 4-point edge, while CNN/ORC had her up 5. Clinton was ahead by 4 with independent voters, Quinnpiac said.

In North Carolina, Trump was up 45-38 among independents, Quinnpiac said. Clinton led overall by 3. Quinnipiac’s polls were conducted Thursday through Tuesday.

In Wisconsin, among independent voters, Clinton was up by 7 over Trump on Wednesday and Thursday. Friday, Trump jumped to a 10 point advantage, then back to 8 in Saturday through Monday interviews.

He also solidified support among Republicans. Nearly three in four backed him Wednesday and Thursday, 87 percent on Friday and 86 percent on Saturday through Monday.
