Video of West arriving at Trump Tower:
He arrived around 9:15 a.m. and said "hey" but did not answer questions thrown at him.
West appeared later with Trump, who told reporters, "Just friends. Just friends. He's a good man, know him well, a long time. We've been friends for a long time."
After several minutes of posing, West was asked why he didn't have anything to say. "I just want you to take a picture right now," he responded.
As they left, Trump hugged West and said, "you take care of yourself. I'll see you soon."
West was taken to UCLA Medical Center in November, just hours after canceling his Saint Pablo tour.
West was rushed by ambulance to UCLA Medical Center from the home of his Hollywood trainer Harley Pasternak on Nov. 21. The trainer, who also works with West's wife, Kim Kardashian, said the rapper was suffering from exhaustion and sleep deprivation.
West went home after being hospitalized for more than a week.
The medical emergency came after several days of bizarre behavior and rants at his concerts, before he canceled his Los Angeles show and then the rest of his current tour.
