Michelle Obama advised Melania Trump and Bill Clinton to just be themselves if their spouse gets elected president.

“In the words of Sasha Obama, I’d say: Do you,” Obama told NBC’s “Today” host Al Roker Friday. “You know, I would just urge the next person coming into this world to make it your own, because it’s believable when it comes from the deepest part of who you are because this is a powerful platform to make a lot of change.” (RELATED: Michelle Obama Makes Fun Of Donald Trump’s Defective Microphone)

The first lady also slammed Donald Trump earlier in the week, when she made fun of the Republican presidential nominee by tapping her microphone at a rally in North Carolina. The comment was in reference to Trump saying after the Presidential debate that his microphone wasn’t working, however the Commission on Presidential Debates has since said that there were issues regarding Trump’s mic.

During the same rally, Obama made fun of Trump’s tweeting at 3 a.m.

“We also need someone who is steady and measured,” Obama said. “Because when making life or death, war or peace decisions a president can’t just pop off or lash out irrationally. And I think we can all agree that someone who’s roaming around at 3 a.m. tweeting should not have their fingers on the nuclear codes.”
