Relentless Donald Trump supporter and conservative media heavyweight Ann Coulter finally has a gripe with the presumptive Republican presidential nominee.

In a series of social media posts, the pundit revealed she isn’t thrilled about the rumors that Trump will name Indiana Gov. Mike Pence (R) as his running mate.

Withholding comment until it's official, but if claims about Pence as VP are correct, boy was I right about this being Trump's first mistake — Ann Coulter (@AnnCoulter) July 14, 2016

Pence is the combo-platter of disaster. For details, see what I just posted on my Facebook page. — Ann Coulter (@AnnCoulter) July 14, 2016

In her Facebook post, Coulter slammed Pence for flip-flopping on gay marriage and being soft on immigration.

“He’s all in for corporate America bringing in as many guest workers as they please to replace American workers,” she wrote.

She continued her tweetstorm with a list of alternative VP picks.

I hope Pence is not true. — Ann Coulter (@AnnCoulter) July 14, 2016

Better VP picks for Trump! Kris Kobach, Scott Brown, Pat McCrory, Mike Crapo, David Clarke, Mike Tyson, my next door neighbor ... — Ann Coulter (@AnnCoulter) July 14, 2016

She also compared the choice to former President George W. Bush’s nomination of White House counsel Harriet Miers for the Supreme Court before he ultimately bowed to critics who questioned her conservative credentials and withdrew the nomination.

Trump has twice Bush's IQ. Why would he pull a Harriet Miers? — Ann Coulter (@AnnCoulter) July 14, 2016

Hey! Maybe Trump should just go ahead and pick Harriet Miers as his Veep! — Ann Coulter (@AnnCoulter) July 14, 2016

And she seemed to take a stab at both New Jersey Gov. Chris Christie (R) and Pence, respectively, with this one:

If Trump just used same Body Mass Index calculator airlines use for stewards & IQ test Walmart uses for clerks, we'd be spared egregious VPs — Ann Coulter (@AnnCoulter) July 14, 2016

Trump is expected to formally announce Pence as his running mate on Friday in New York City.

Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims ― 1.6 billion members of an entire religion ― from entering the U.S.
