Donald Trump has some callous words against U.S. President Barack Obama.

In an interview with ABC News, the Republican presidential candidate said that Obama "set a very poor standard" for African Americans, adding that he "has done nothing" for them.

"You look at what's gone on with their income levels. You look at what's gone on with their youth. I thought that he would be a great cheerleader for this country. I thought he'd do a fabulous job for the African-American citizens of this country," Trump told ABC News.

The real estate magnate also said that the African-American community has unemployment problems, and Obama has performed "poorly" in this matter, the news outlet added. Trump claimed that he has a strong chance of winning the African-American vote, as well as the Hispanics' favor.

This isn't the first time that Trump aired out his disappointment over Obama's presidency. In Nov. 2014, he tweeted, "Sadly, because president Obama has done such a poor job as president, you won't see another black president for generations!"

Earlier this week, Gawker revealed a cellphone number that belongs to Trump. The businessman's camp confirmed that the mobile digits were indeed used by him, but not anymore, Politico wrote. A call to the number directs to a voice mail that says, "Please leave your name and message and we'll get back to you shortly," the news outlet added.

"It's a very old number. This is not one he uses. Mr. Trump has several numbers so this is not an issue," his campaign told Politico.

The release of Trump's cellphone number comes after he publicly revealed fellow presidential hopeful Sen. Lindsey Graham's own mobile digits. Gawker reasons that given Trump has decided "that opening up a direct, personal channel of communications between his supporters and his primary opponents is a noble campaign tactic," it's only reasonable that Republican primary voters are also able to talk to Trump.

Trump Leads in New Poll

Two polls unveiled on Monday, one from Fox News and the other from University of New Hampshire's WMUR, showed that Trump is leading over the other presidential candidates.

Fox's poll belongs to the five national polls that the network will base on as to who will be a part of the debate in Cleveland on Thursday, NY Times wrote. The poll indicates that Trump got 26% of self-identified primary voters, which is an increase from last month's 11%. In WMUR's poll, Trump has 24% of the votes.

Another poll from NBC News/Wall Street Journal released on Sunday indicates 61% of a total of 250 Hispanic voters do not support Trump, Washington Post reported. In June, Trump referred to Mexican immigrants as rapists, drug dealers, and criminals.
