Michael Moore teases 'secret project' aimed at Donald Trump, Roseanne Burr: 'They will rue the day they knew me'

Fahrenheit 9/11 director Michael Moore teased a “secret” documentary involving Donald Trump and Roseanne Barr on Wednesday. He shared on Twitter a throwback clip of him as a guest alongside Trump on The Roseanne Show, Barr’s talk show in the late 90s. The tweet was accompanied by the caption: “I know Roseanne. And I know Trump. And they are about to rue the day they knew me…”
