In a Fox News interview that aired before the Super Bowl, Bill O'Reilly asked President Trump if he "respected" Russian President Vladimir Putin. When Trump said he did, O'Reilly responded, "Putin's a killer."
That was enough to prompt Russia to ask for an apology on Monday, USA Today reports.
Trump's response was controversial in its own right as he said, "We've got a lot of killers. You think our country's so innocent?"

We would prefer to hear apologies addressed to the president from such a respectable television network.
Putin spokesman Dmitry Peskov told reporters the statement was "insulting and impermissible."
Trump's relationship with Putin has drawn questions and criticism from both parties. Trump got a letter from Putin in December, which he released to the public, saying, "His thoughts are so correct."
A day after former President Obama hit Russia with sanctions for its interference in the 2016 elections, Trump tweeted out praise for Putin, calling him "very smart!"
Great move on delay (by V. Putin) - I always knew he was very smart!— Donald J. Trump (@realDonaldTrump) December 30, 2016
Here's the "very smart" tweet.
But there are still tensions between the two superpowers. Vice President Pence said Trump was "troubled" by Russia's military activity in Ukraine, where Russian-backed forces and Ukrainian forces have clashed recently.
