President Donald Trump has long claimed that any investigation into his administration was a “witch hunt.” But as polls have shown growing support for impeachment, he has now escalated his rhetoric against checks and balances.

On Tuesday, Trump claimed that there was a “coup” occurring in America.

A coup d’état refers to an illegal overthrow of an existing government.

However, an impeachment proceeding is not illegal — it is written in the Constitution — and it wouldn’t overthrow the existing government as Republican Vice President Mike Pence would ascend to the presidency.

That Trump was unfamiliar with the situation provided much fodder for the commander-in-chief to be mocked online. Here’s some of what people were saying:

….People, their VOTE, their Freedoms, their Second Amendment, Religion, Military, Border Wall, and their God-given rights as a Citizen of The United States of America!

Their VOTE – You had 3 million less of 'em.

Their Second Amendment – No one is taking away guns. We all just want common sense gun laws.

Religion – You banned Muslims.

Military – You took money away to build your:

Border Wall – Which Mexico isn't paying for.

I, the president, have determined that WITCH HUNT is no longer working against the bad fake polls so I will therefore road test new words in real-time like COUP to see what sticks with real Americans and Jesse Waters. https://t.co/cYtF30WSt2

Every time the President Tweets about a coup or a civil war, he is making Vladimir Putin’s wildest dreams come true.

The sooner we remove him from office the better.

What’s nutty about this “coup” stuff is that it Trump gets removed from office for being a crook … Mike Pence becomes president.

There’s no Democratic takeover, no national unity government, no caretaker administration, no snap election … Mike Pence.

Impeachment is a constitutional remedy, not a COUP.

And the last time the People used their VOTE, they used their God-given rights as Citizens of the United States of America to elect Democrats who promised to hold this president accountable.

This is unhinged and dangerous. pic.twitter.com/JMQ4KqZZjO

It’s a coup for Congress to use its constitutional powers? https://t.co/DPPzXmUUbw

Trump has in the last couple days:

-Suggested Schiff should be arrested for “treason”
-Endorsed a comment suggesting his removal could cause Civil War
-Compared impeachment — a process defined in the Constitution — to a “coup.” https://t.co/nLnUgcPr5s

This is the most formal coup I’ve ever heard of. You ever hear of a coup that has due process and investigations? Isn’t it usually a smash and grab? https://t.co/cJFLlSGpN9

If it was a coup, Congress wouldn't be going to the trouble of applying the legal, constitutional mechanism created by the Founders for the explicit purpose of removing a president who violates the public trust. https://t.co/UbaZPjj0EK

He’s no “victim.” He’s a corrupt con man. It’s no “coup.” It’s called the Constitution. https://t.co/UCwx7ksqAX

Trump is now claiming that he's the victim of a coup, after demanding the arrest of a U.S. congressman for treason, suggesting that the result could be a civil war, and deploying federal agencies to target his political opponents with the full force of the U.S. government.

— Matthew Gertz (@MattGertz) October 1, 2019

And the circle is now complete: Trump repeats the claim, which has been all over right-wing media in recent days, that he might be the victim of a "coup." https://t.co/lCBJ7oRki2

The coup happened on November 8, 2016, when you had Russia install you as President*.

We're not letting you do it again in 2020.

Enjoy impeachment.

Trump doing his best to incite a violent response by his followers. Trump should be impeached and removed for this alone!!!

— (((DeanObeidallah))) (@DeanObeidallah) October 2, 2019

No, it is an impeachment, and it’s right there in the Constitution.

Next you’ll be saying the election is a coup.

This is the rule of law.

— Michelangelo Signorile (@MSignorile) October 2, 2019

It isn't a coup, it's the process outlined in Article II, Section 4 of the Constitution. You know, that document you swore you would uphold?

Call it whatever you want. You are a psychopath and your time as wannabe dictator is almost at an end, dick.
