16-year-old Greta Thunberg has one powerful supporter in Michelle Obama. The former First Lady came to the defense of the young activist shortly after President Trump tweeted saying that Geta needs to "chill." Obama tweeted at Thunberg on Thursday night with several words of encouragement.
"@GretaThunberg, don’t let anyone dim your light. Like the girls I’ve met in Vietnam and all over the world, you have so much to offer us all. Ignore the doubters and know that millions of people are cheering you on," Michelle wrote.
