Former President Donald Trump was heavily trolled on Twitter on Sunday after he accused his former lawyer Michael Cohen of being a “cereal liar.”

On his social media platform, Truth Social, Trump posted: “The jailbird Michael ‘Longhead’ Cohen is a cereal liar. He hid a wire in MANY of our at the time cordial perfect meetings. He should never be trusted yet SDNY Alvin ‘Cannot’ Bragg and the low IQ grand jury has taken him at his word!!! We need to TAKE OUR ONCE GREAT AMERICA back!!!”

A screenshot of the message soon went viral on Twitter, after which the 45th POTUS was heavily mocked.  “A ‘cereal’ Liar? Does that mean Donald Trump thinks Michael Cohen @MichaelCohen212 likes Lucky Charms but says he likes Cheerios instead? P.S. – I have no idea what Trump means by ‘Longhead’ and don’t want to guess. But growing up in the South in the 60s and 70s – that wasn’t an insult. Yes. A joke,” one user wrote.

Another said, “‘Cereal Liar’ How was this man our President?” A third wrote, “Omg! Just stop, you dumbshit! It’s serial not cereal! Lololol!! Everyday he comes out with a new way of showing us just how stupid he is!” One more tweeted, “Trump never learned to spell A ‘cereal’ liar is someone who works for Kellogg Who else thinks that to be President the MINIMUM requirement should be to pass a fourth grade spelling test?”

A Twitter user said, “Does this mean Michael Cohen lies about cereal? Cheerios? Oatmeal?” Another quipped, “1. Longhead? 2. Cereal? 3. SDNY is federal. Bragg is the DA. 4. Insulting the grand jury?”

Trump is seeking at least $500m in damages from his ex-lawyer in a lawsuit after Cohen testified before the Manhattan grand jury that indicted Trump. In an arraignment in Manhattan criminal court, Trump pleaded not guilty to 34 felony charges earlier this month.

The lawsuit accused Cohen of breaking a non-disclosure agreement which was a condition of his employment. He was accused of violating ethical standards for lawyers and also “spreading falsehoods” about the ex-president “with malicious intent and to wholly self-serving ends”.
