Did President Trump Mock Teen Climate Activist Greta Thunberg?

President Trump is taking on teen climate fighter Greta Thunberg after their frosty encounter at the United Nations Monday. The Swedish 16-year-old criticized world leaders for their lack of action to fight climate change. She has not mentioned Trump by name, but the president has suggested climate change does not exist or is not an immediate threat. On Monday night, the president tweeted, “She seems like a very happy young girl, looking forward to a bright and wonderful future, so nice to see.”
