President Trump made a pledge to black supporters in Atlanta Friday that the 'best is yet to come' if they stuck by his side through the next election cycle.

He slammed Democrats for letting down black communities, trapping black children in failing public schools.

'The betrayal of the black community is unbelievable,' Trump said. 'You have the worst schools than anybody in the country by far.'

He went as far to say that Democrat prioritized undocumented immigrants over black citizens, who have long been a dependable Democratic voting bloc.

'Democrats care more about illegal aliens than African-American citizens, or our military, or citizens all over the place,' Trump said.

Trump's speech was billed as a 'Black Voices for Trump' kick-off event through his 2020 re-election campaign.

The president's opening act was his only black cabinet member, HUD Secretary Ben Carson.

'Today they say if you are a conservative you're somehow an Uncle Tom, you're a horrible person,' Carson told the crowd. 'What a bunch of crap,' the mild-mannered ex-brain surgeon added.

'I only care about what God thinks,' Carson said.

Vice President Mike Pence also spoke, while a number of prominent black supporters - Diamond and Silk, Katrina Pierson, Paris Dennard, Alveda King and Herman Cain - were in the crowd.

Trump started his own speech by asking how to best identify the group.

'What do you prefer - "Blacks for Trump" or "African-Americans for Trump?"' the president asked the audience. A loud 'Blacks for Trump' cheer started in response, so Trump sort of stuck with that.

He also tickled the crowd by commenting on his shoot-from-the-hip speaking style.

'I do my best work off-script,' he said. 'I hate to say this, but I also do my worst work off-script.'

'It makes things very exciting,' Trump added.

Most of the meat of the speech was the president's usual boasts, though he made the point - as he did during the 2016 cycle as well - that black voters really have nothing to lose.

'It's amazing that you've stayed so long to be honest,' he said, commenting on the high number of African-Americans who vote Democratic.

In 2016, Hillary Clinton won 88 percent of the black vote, while Trump got just 8 percent.

'And ladies and gentleman of the African-American community, I just want to tell you really, really strongly, the best is yet to come,' Trump vowed as he wrapped up his remarks.

He said that next time he'd hold a Blacks for Trump event in a bigger room, commenting on how they needed overflow.

A spokesperson for the campaign has yet to respond to a request for comment on attendance numbers.

'You're very, very, very special people,' Trump went on.

'What has happened in the last three years for the black community, the African-American community has been really incredible and it is my honor to have been there with you,' the president said.

Also on Friday, Trump launched what he's dubbing the #MAGAChallenge on Twitter, which is geared to black and young voters.

The president linked to a popular music video from supporter Bryson Gray, who calls himself 'MAGA Boy.' In the video, Gray raps in a giant 'Make America Great Again' hat about how he was told he shouldn't support Trump because he's black.

'I will be announcing the winners of the #MAGAChallenge and inviting them to the White House to meet with me and perform,' Trump tweeted. 'Good luck!'
