The grandmother who was released from prison by President Donald Trump -- following a push by Kim Kardashian West -- took the stage on the final night of the Republican National Convention to make her case for Trump.

Alice Marie Johnson, who was serving a life sentence in federal prison for a non-violent drug arrest before being released in 2018, talked about her freedom and the support she has received from the president. Johnson's plea for clemency was rejected by the Obama administration, but Trump granted the request after West brought it to his attention.

"I was once told that the only way I would ever be reunited with my family would be as a corpse," Johnson told the RNC crowd Thursday. "But, by the grace of God and the compassion of President Donald John Trump, I stand before you tonight, and I assure you I am not a ghost."
