Donald Trump Jr mocked for trying to troll Ketanji Brown Jackson

Donald Trump Jr was quickly panned after the former president’s son attempted to weigh in on the third day of Judge Ketanji Brown Jackson’s confirmation hearings.

The tweet, which appears to mock Ms Brown for declining to comment on questions that fall outside her area of expertise as a federal judge and lawyer, begins with Mr Trump writing out the rudimentary maths equation “1 + 1” but is then followed by a series of question marks.

“I have no idea what the answer is… I’m not a mathematician!!! #JudgeKetanjiBrownJackson,” Mr Trump writes.
