Speaking after a long day of jury selection and ground rules (with more than 50 jurors dismissed), Trump walked out of the courtroom and expressed his obvious displeasure.

"As you know my son is graduating from High School, and looks like the judge will not let me go to the graduation for a son who's worked very, very hard," Trump said, adding that he was "looking forward for years to having graduation with his mother and father there," adding that the trial is a "scam" and a "political witch hunt."

Judge Juan Merchan also won't allow Trump to attend a Supreme Court hearing in DC regarding immunity.

"We got a real problem with this Judge," Trump continued, adding "that I can't go to my son's graduation, or that I can't go to the United States Supreme Court, that I'm not in Georgia or Florida or North Carolina campaigning like I should be... it's perfect for the radical left Democrats - that's exactly what they want," he continued, adding that it's "election interference."

Update (1200ET): Monday's 'hush money' trial against former President Donald Trump has begun, with jury selection and a discussion over evidence on the table. To get the blow-by-blow throughout the day, follow this thread on X by Inner City Press.

The case stems from a $130,000 payment made by Trump's former lawyer, convicted felon and admitted liar Michael Cohen, to adult film actress Stormy Daniels at the end of the 2016 election in an alleged scheme to buy her silence. Trump is required to be present for the trial, which will take place four days a week and could last up to two months.
