Former Obama official John Kerry is calling on President Trump to resign. The remarks come by Kerry at the world economic forum held in Davos, Switzerland.

According to The Hill:

Former Secretary of State John Kerry had a simple message for President Trump on Tuesday, saying he should “resign.”

Kerry was speaking on a discussion panel at the World Economic Forum in Davos, Switzerland, when he was asked what his message to Trump would be, according to CNBC.

Kerry was at first hesitant to answer the question, saying Trump “doesn’t take any of this seriously.”

“He doesn’t have an ability to have that kind of conversation,” Kerry said after debating whether to answer or not.

President Trump was supposed to attend the conference but stayed in Washington amid the government shutdown and battle on immigration.
