Michael Knowles argued for Fox News this week that Kyle Kashuv was only "espousing conservatism" when he was rejected by Harvard for using the N-word at least 11 times and calling to "kill all the f*cking Jews."

In an op-ed on the Foxnews.com website, Knowles asserted that Kashuv is being singled out by Harvard because he has conservative views.

"The cruel irony is that, while there is no evidence that Kyle Kashuv harbors any actual racial bigotry, there is plenty of evidence that Harvard does," Knowles wrote. "Plaintiffs in a major racial discrimination lawsuit against the university introduced evidence last year demonstrating that Harvard systematically disadvantages Asian-American applicants."

President Donald Trump's acting defense secretary abruptly resigned after an FBI investigation further delayed his confirmation hearings.

Patrick Shanahan has headed the Department of Defense since January, after James Mattis resigned, but the Pentagon has been fielding questions from the media about his personal life -- including accusations of abuse from his ex-wife, who was also arrested as part of a domestic dispute.

"Acting Secretary of Defense Patrick Shanahan, who has done a wonderful job, has decided not to go forward with his confirmation process so that he can devote more time to his family," Trump tweeted.

President Donald Trump -- whose rallies are still punctuated with "lock her up" chants" -- may face turnabout from his Democratic rivals.

Some Democratic candidates are openly threatening Trump with prosecution once he's out of office, and those taunts are alarming to some law enforcement veterans, reported Politico.

“Presidents aren’t supposed to suggest there be investigations or prosecutions of particular people, let alone their political rivals,” said Matt Axelrod, a former Justice Department senior official under Obama. “President Trump has flagrantly and repeatedly violated that norm, but that doesn’t mean the norm has been obliterated.”
