If we've learned anything from the 2016 election, it's that every candidate must answer for and denounce the words of their allies and supporters. For Trump, this was true no matter how tenuous the connection was. Even if there was no connection, he was asked - repeatedly - to reject statements made by every last weirdo who said they were voting for him. Heck, even after Trump denounced the crazies, he was badgered to denounce them again.
