Fans of David Muir can't get enough of him, whether he's on camera or behind-the-scenes. Last week, the ABC World News Tonight anchor was traveling in Beijing, for Donald Trump's two-day visit to meet with Chinese president Xi Jinping. And as he made his return stateside, fans were quick to congratulate him over a job well done. Following David's return home, he took to Instagram and shared a photo of him busy at work.
