U.S. Secretary of State Rex Tillerson has joked that he has felt the need to “curl up in a ball.” 
ABC News tweeted a video of him making the comment during a visit to a park in Geneva, Switzerland. The footage shows the cabinet secretary stopping to take a closer look at a statue of what appears to be people huddling together. 
“Yeah, some days I feel like I need to do that. Curl up in a ball,” Tillerson noted.
He then walks away, laughing. 
While no further explanation was given, Tillerson has had some notable challenges this month including an NBC News report claiming he had called President Trump a “moron” and had seriously considered resigning from his cabinet position over the summer.
Tillerson held a press conference soon after and said, in part, “To address a few specifics that have been erroneously reported...I have never considered leaving this post.” 
However, he seemed to sidestep a question about calling Trump a moron, saying, “I’m not going to deal with petty stuff like that.” 
While the president backed Tillerson in an interview, he also joked about comparing their IQ scores, adding, “I can tell you who is going to win.”
