7 things to know now: Trump regrets remarks; Clinton Foundation; Amber Heard

What to know now:

1. Trump on harsh remarks: Donald Trump said on Thursday he regrets remarks he made in the past that "may have caused personal pain."  "Sometimes, in the heat of debate and speaking on a multitude of issues, you don't choose the right words or you say the wrong thing," the Republican nominee said at a campaign stop in Charlotte, N.C.  "I have done that, and I regret it, particularly where it may have caused personal pain. Too much is at stake for us to be consumed with these issues." Trump did not elaborate on which remarks he regrets.

2. Clinton up by four: If the presidential election was held today, Democratic nominee Hillary Clinton would edge out Donald Trump in a four-way match-up with Libertarian candidate Gary Johnson and Green Party nominee Jill Stein. According to the Pew Research Center, 41 percent of those surveyed would choose Clinton, 37 percent Trump, 10 percent Johnson and 4 percent Stein.

3. Swimmers home: Gunnar Bentz and Jack Conger, the two American Olympic swimmers who were pulled off of a plane Thursday in Brazil after a story of an alleged robbery was questioned by authorities, are now back in the United States. Police in Brazil said Bentz, Conger, and Gold Medal winners Ryan Lochte and Jimmy Feigen had never been held at gunpoint following a night at a club, as they claimed, but, instead were intoxicated, stopped at a service station to use the bathroom, then proceeded to vandalize the business. As they tried to leave the club, police say, they were stopped, questioned by security guards and ordered to pay for the damage. Lochte had claimed the group was pulled over and robbed at gunpoint. The United States Olympic Committee apologized to the people of Brazil on behalf of the four swimmers. ABC News reported Feigen has agreed to pay $11,000 to a Brazilian charity to avoid prosecution in the case.

4. Clinton Foundation: Bill Clinton said Thursday that if Hillary Clinton wins the presidency in November, the Clinton Foundation will no longer accept foreign and corporate donations. Addressing charges by Republicans that the foundation received donations in exchange for access to Hillary Clinton when she was secretary of state, the former president said he would resign from the board and would only accept contributions from independent charities and U.S. citizens if Hillary Clinton is elected president.

5. Leverage, not ransom: On Thursday, the State Department confirmed that a $400 million cash payment to Iran in January was, in fact, tied to the release of four American being held in the country. According to State Department spokesman John Kirby, while  negotiations over the United States' return of Iranian money from an account frozen in the 1970s was not conducted together with negotiations to release the four Americans, the United States did withhold the delivery of the cash until the four left Iran. The payment  -- stacks of cash -- was made the day the prisoners were released. President Obama denied earlier this month that the payment was ransom for the four.
