Stephen Colbert has been going hard with the RNC coverage this week. On Monday, Colbert trotted out his Colbert Report alter-ego and teamed up with Jon Stewart for a few fantastic segments lampooning Trump. Tuesday night, Colbert kept up his winning streak by bringing actress and Broadway star Laura Benanti on for a pitch-perfect impression of Melania Trump.Benanti doesn't just look the part—she completely nails Melania's accent and mannerisms as she defends the wannabe first lady's recent plagiarism accusations. The whole thing is genius, and made even more impressive by the fact that it must have come together completely last minute, since Melania gave her Obama-aping RNC speech only 24 hours before Benanti went on the air portraying Trump's wife.Give it a watch above, and keep an eye peeled for whatever else Colbert has up his sleeve this week. It's sure to be good.Read: The Trump Campaign Swears Melania Didn't Plagiarize Michelle Obama
