Did anyone catch Trump talking, was shown earlier on Hannity, where he kept saying something about a bad business deal with Mueller. I did some digging and found he apparently was once a member of one of the Trump golf clubs and supposedly didn't pay his dues.
"…the most eye-catching alleged conflict of interest involves a purported dispute between Mueller and the Trump National Golf Club in Sterling, Virginia, in October 2011. President Trump claimed Mueller resigned his membership at the club due to the alleged disagreement over fees and believes he still holds a grudge against him over the matter.
Mueller, who was FBI director at the time of the alleged dispute, denied the incident and any potential hard feelings.
