Kardashian West, who met with the president to lobby on behalf of Johnson, tweeted that the prisoner's release was the "BEST NEWS EVER!".
At an emotional reunion with her family outside an Alabama prison, the former prisoner thanked Mr Trump and Kardashian West, saying she was "free to live life and free to start over". Johnson, 63, was serving a life sentence without the possibility of parole after being convicted of a first-time nonviolent drug offense. "We are optimistic about Ms. Johnson's future and hopeful that she-and so many like her-will get a second chance at life". "And in Alice's case, it is a punishment that absolutely did not fit the crime".
"I believe because I'm recognized now and my case is magnified through media, it has caught the attention of others", Johnson said.
Trump last week pardoned conservative commentator and filmmaker Dinesh D'Souza, convicted of making illegal campaign contributions.
CNN have also released footage of Alice being reunited with her family, following her release from prison.

As clemency petitions work their way through the system, the president routinely denies the "vast majority" of requests, a White House official said.
Also, Kim Kardashian West will be meeting the lady she helped to free from prison.
"She has truly been relentless in her fight for me", Johnson said of Kardashian West. "This is one case that went viral so a lot of people were made aware of it", Guster said. "When I just popped up on her phone, she said it was a moment where she knew ... this is a person that she needs to do something [for]".
"You now have a president who effectively thinks he can do things by pardons". Thank you for taking the time to look at my case, and feel like I deserve a second chance in life.
"Don't make a permanent decision that can change your life forever based on a temporary situation", she said looking back at her past. He pardoned the late heavyweight boxer Jack Johnson, controversial former Arizona Sheriff Joe Arpaio and Lewis "Scooter" Libby, a former top aide to then-Vice President Dick Cheney.
