The meeting that will take place at the White House this week between Trump and Ye is said to concern topics of social issues like prison reform, employment in the manufacturing industry and gang violence.
West also banged his fist on the Oval Office's famed Resolute Desk and discussed his bipolar diagnosis.
Trump recently tweeted praise for West, who closed a "Saturday Night Live" show wearing a "Make America Great Again" hat and delivering an unscripted pro-Trump message after the credits rolled.
In an interview with Fox News before the meeting, Trump said the justice system was "very unfair to African-Americans it's very unfair to everybody".
Addressing Mr Trump, he added: "There was something about when I put this hat on it made me feel like Superman". "I'm talking about the it-will-never-happens of the world, people in high school told you things would never happen". Supporters of West's music have described him as a political sellout.
The School of Rock actress then urged young people to vote, saying that if young people don't want to listen to her, they should at least listen to pop star Taylor Swift.
Silverman also went after Brett Kavanaugh, saying, "If I think of his frowny pink face and his Pert Plus hair one more time I'm gonna puke".
"I can not vote for someone who will not be willing to fight for dignity for ALL Americans, no matter their skin color, gender or who they love".
