Donald Trump says he regrets remarks that 'caused personal pain'

Republican presidential candidate Donald Trump included uncharacteristic comments of regrets and visits in another revamp of an unsettling political campaign.

The presidential contender for the GOP party almost apologized when he offered words of regrets for comments he previously made.

"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. I have done that," the former host of "The Apprentice" told the crowd in Charlotte, North Carolina on Thursday evening. "And believe it or not, I regret it — and I do regret it — particularly where it may have caused personal pain."

The 70-year-old real estate mogul did not specify which of the previous remarks he regretted, but those he made against the American soldier killed on duty in Iraq, Army Capt. Humayun Khan, and the tirade he exchanged with the Muslim American parents proved most damaging, according to the post-convention poll conducted by Washington Post–ABC News.

The poll showed that his Democratic rival, Hillary Clinton, benefitted from her party's National Convention and also from Trump's incendiary remarks, making his decisions his own undoing.

According to the Associated Press, Trump's finally shown he's serious about winning the race to the White House by delivering formal speeches and even following a teleprompter.

Trump also visited the flood victims of southern Louisiana on Friday to express solidarity and provide relief effort.

"Nobody understands how bad it is," he told reporters while unloading a truck of supplies. "It's really incredible, so I'm just here to help," the presidential candidate added.

That same day, Trump accepted the resignation of his second campaign chairman Paul Manafort, who's accused of working for a pro-Russian political party in Ukraine. His new campaign manager, Kellyanne Conway, praised Trump for leading the overhaul.

"All the people who have been saying, 'Let's get Trump to pivot, let's get him to be more presidential.' That is presidential," Conway told ABC in an interview.
