The remarks took a more controversial turn when Trump said Clinton's Secret Service detail should stop carrying their weapons.
"We'll see what happens to her," Trump said.
Many people on Twitter interpreted the remark similarly to a joke he made in August, which many took to be a joke about assassinating Clinton.
It's one of a couple Trump-related controversies that roiled the internet Friday.
Many complained about Trump's appearance Thursday on The Tonight Show, where host Jimmy Fallon was seen as too accommodating of him.
