Washington was at the White House to see the celebrate a prison reform bill, the First Step Act, which is focused on inmate rehabilitation.

He wrote: 'I voted for 44 twice. I even checked my emails in his Senate Office while lobbying for Salone to be given another chance to rebrand.

'Not once in 8 years was I given any support regarding Africa or the Black Agenda, but 45 invites me to the WH to celebrate the #FirstStepAct.'

Responding to the backlash Washington hit back, writing: 'I may have 99 problems with 45, but mass incarceration ain't one of them.'

Congress passed legislation last year called the First Step Act that gives judges more discretion when sentencing some drug offenders and boosts prisoner rehabilitation efforts.

The effort drew strong support from Republicans and Democrats worried that mandatory minimum laws had generated unfair sentences in many drug-related cases.

He said a 'Second Step Act' will focus on 'successful re-entry and reduced unemployment for Americans with past criminal records.' His goal is to cut that unemployment rate for ex-prisoners to single digits within five years.

Washington shared pictures and videos of himself from inside The East Room and added: 'Those who know, know that I'm not a Democrat or a Republican. I will work w/h anyone as long as things get done.'

Speaking directly to Trump he said: '@realDonaldTrump you freed 3,000 Federal Prisoners, got 16,000 in drug rehabilitation programs and now you just need to deliver.'

One Twitter user wrote: 'You cannot be serious! Trump is undoing a problem HE created! Barack is the best that ever did it! That buffoon you are sucking up to has not once condemned the white supremacists who have killed all in the name of MAGA'
