Donald Trump, the King of Twitter, has had plenty to say about Fox News anchor Megyn Kelly. He has accumulated 117 tweets in his Kelly archive since 2011. At first, they were professional and appropriate.

But then came that infamous Fox News debate of August, 2015, when Kelly started off by asking Trump questions about his misogynistic attitude towards women.

And it was all downhill from there.

Here are the ten worst tweets that Trump has leveled against Megyn Kelly since then. I had a really difficult time limiting my list to just ten.

First, the infamous “blood” tweet, which Trump revised to indicate “NOSE,” rather than another body part.

Re Megyn Kelly quote: "you could see there was blood coming out of her eyes, blood coming out of her wherever" (NOSE). Just got on w/thought

They continue.

"@ColeHudson68: @megynkelly @FoxNews @theBlaze @greta @OreillyFactor Megyn needs to go back on vacation. What a waste of an hour on Fox."

Do you ever notice that lightweight @megynkelly constantly goes after me but when I hit back it is totally sexist. She is highly overrated!

— Donald J. Trump (@realDonaldTrump) September 23, 2015

.@megynkelly recently said that she can’t be wooed by Trump. She is so average in every way, who the hell wants to woo her!

Suddenly the Trump Twitter war on Megyn Kelly has ramped up again over the weekend, for reasons unknown. Or maybe for no reason at all. With Trump’s erratic behavior, who knows?

Here are the remaining four of the ten worst:

Everybody should boycott the @megynkelly show. Never worth watching. Always a hit on Trump! She is sick, & the most overrated person on tv.

"@Ma1973sk: Actually, no @FoxNews, @megynkelly has a sick obsession with Trump. Every day, every show, trashing, negative, hate.

— Donald J. Trump (@realDonaldTrump) March 19, 2016

Crazy @megynkelly says I don't (won't) go on her show and she still gets good ratings. But almost all of her shows are negative hits on me!

— Donald J. Trump (@realDonaldTrump) March 19, 2016

If crazy @megynkelly didn't cover me so much on her terrible show, her ratings would totally tank. She is so average in so many ways!

This recent flurry of obsessive tweets made by Trump against Megyn Kelly caused Fox News to fire back at the blowhard billionaire, stating:

“Donald Trump’s vitriolic attacks against Megyn Kelly and his extreme, sick obsession with her is beneath the dignity of a presidential candidate who wants to occupy the highest office in the land. Megyn is an exemplary journalist and one of the leading anchors in America – we’re extremely proud of her phenomenal work and continue to fully support her throughout every day of Trump’s endless barrage of crude and sexist verbal assaults. As the mother of three young children, with a successful law career and the second highest rated show in cable news, it’s especially deplorable for her to be repeatedly abused just for doing her job.”

Janice Dean, meteorologist at Fox News, found Trump’s tweets against her colleague to be “disturbing” and “not presidential.”

This obsession with @megynkelly is disturbing and not presidential. Please stop. @realDonaldTrump https://t.co/ARkc2s6nS8

Glenn Beck, writing at his Facebook page, advised Trump in an open letter to “leave Megyn Kelly alone” after reading Trump’s “really sad and sick tweets” against her. He asked, “Mr. Trump, what would you do if someone obsessively stalked your daughter on Twitter for months after a minor disagreement as you have had with Megyn?”

New York Times conservative columnist Ross Douthat mused that maybe Trump had an ulterior motive behind his obsessive behavior:

Trump envisions his wedding to Megyn Kelly as the made-for-TV highlight of his presidency-for-life.

— Ross Douthat (@DouthatNYT) March 19, 2016

This is not the first time Trump has harassed a woman journalist who crossed him. British journalist Selina Scott interviewed him for a 1995 documentary, which Trump found to be negative. He went ballistic and stalked her for 20 years until she finally threatened legal action.

The one with the sick obsession is not Megyn Kelly, it’s Donald Trump. Such behavior is undignified and unbecoming to the average individual, much less to a man who seeks to attain the highest office in the land. Trump doesn’t need more whooping sycophants. He needs psychological intervention. And he absolutely doesn’t deserve the presidency.
