Donald Trump, unhappy about his treatment by Fox News during and after the first Republican presidential debate Thursday night, took to Twitter to vent his frustration, highlighting a tweet calling moderator Megyn Kelly a "bimbo" and calling pollster Frank Luntz a "slob" and a "clown."

During the debate, Kelly confronted Trump on previous sexist comments he has made. And after the debate, Fox ran a focus group led by Luntz in which voters panned the billionaire's performance.

At about 3:23 am Friday morning, Trump started tweeting out his dissatisfaction.

"The biggest loser in the debate was @megynkelly," read one tweet cited by Trump's official account. "You can't out trump Donald Trump. You will lose!"

Another tweet read, "Fox viewers give low marks to bimbo @megynkelly will consider other programs!"

Trump then tweeted, "@FrankLuntz is a low class slob who came to my office looking for consulting work and I had zero interest. Now he picks anti-Trump panels!"

After Luntz tweeted, "I'm getting a lot of @megynkelly hatemail tonight," Trump responded, "She is totally overrated and angry. She really bombed tonite."

He added, ".@FrankLuntz I won every poll of the debate tonight by massive margins @DRUDGE_REPORT & @TIME so where did you find that dumb panel."

He also tweeted, "Wow, @megynkelly really bombed tonight. People are going wild on twitter! Funny to watch." And continuing, ".@FrankLuntz, your so-called "focus groups" are a total joke. Don't come to my office looking for business again. You are a clown!"

But, lest anybody think he didn't enjoy the debate, he wrote, "I really enjoyed the debate tonight even though the @FoxNews trio, especially @megynkelly, was not very good or professional!"

Here is the tirade.
