With less than a week until Election Day and opinion polls showing a tight race, Hillary Clinton and Donald Trump are shifting their campaigns into high gear and visiting states crucial for a White House win.
Republican Trump was in Eau Claire, Wisconsin, Tuesday night, urging Democratic voters who have already cast early-voting ballots for Clinton to take advantage of a state election law and change their decision.
He made the same appeal to voters in other states, who he says now have "buyer's remorse."
During a stop in Pennsylvania, another important battleground state, Trump told supporters that if he is elected, he will call a special session of Congress to repeal the Affordable Care Act, better known as Obamacare. Trump has called the health-insurance program a disaster and promised to come up with his own plan.

FBI Director James Comey's announcement last week that his agents are reviewing newly discovered emails from Clinton’s time as secretary of state has given Trump new fodder with which to suggest his opponent lacks honesty and trustworthiness.
Comey declared nearly four months ago that the FBI had fully reviewed the Clinton emails and found no basis for charges against her.
Clinton, who has said Comey's announcement so close to the November 8 election was "outrageous," campaigned in Florida on Tuesday, where she said Trump's treatment of and comments about women were "demeaning, degrading and insulting."

Clinton said that while she spent the last 30 years as a lawyer, first lady, U.S. senator and secretary of state, Trump was using his celebrity status as an excuse to assault women. She called him a bully.
President Barack Obama campaigned for Clinton in Columbus, Ohio, on Tuesday — another state where the polls are close.
He said a person's character does not change once an election is over. If Trump is elected, Obama predicted, he will continue to disrespect women and working people in the White House, just as he has during the campaign.

The president said calling women "pigs," "dogs" and "slobs" is not normal behavior.
The latest polls of likely voters show the race between Clinton and Trump is too close to call with the two main third-party candidates, Libertarian Gary Johnson and the Green Party's Jill Stein, among the choices given to respondents.
On Wednesday, Clinton goes to Arizona. The state is traditionally Republican, but a growing Hispanic population there resents Trump's tough anti-immigration stance and his vow to build a wall along the U.S.-Mexican border.
