Vladimir Putin is mad.

Last night, on Fox News, Bill O’Reilly referred to Mr. Putin as “a killer.” He then asked President Trump his opinion of Putin to which he replied:

“There are a lot of killers. You think our country’s so innocent?”

President Trump is getting hammered in the media today for the quote. But it’s true. America has done things that all of us would consider necessary, but not ideal. It’s how all countries operate geopolitically.

And now, Putin is demanding an apology for the implication from Fox.

Reuters reported:

The Kremlin said on Monday it wanted an apology from Fox News over what it said were “unacceptable” comments one of the channel’s presenters made about Russian President Vladimir Putin in an interview with U.S. counterpart Donald Trump.

Fox News host Bill O’Reilly described Putin as “a killer” in the interview with Trump as he tried to press the U.S. president to explain more fully why he respected his Russian counterpart. O’Reilly did not say who he thought Putin had killed.

“We consider such words from the Fox TV company to be unacceptable and insulting, and honestly speaking, we would prefer to get an apology from such a respected TV company,” Kremlin spokesman Dmitry Peskov told reporters on a conference call.
