The two initially agreed Bowers would be paid $250,000 for his individual services, a figure that “delighted” Trump, one of the sources said.

However, Trump didn’t realize Bowers hadn’t included additional expenses — including more lawyers, researchers and other legal fees that would be accrued on the job.

He was said to be livid when Bowers came back to him with a total budget of $3 million. Trump called the South Carolina attorney and eventually negotiated him down to $1 million.

All of this infuriated Trump and his political team, who think the case will be straightforward, given 45 Republican senators already voted to dismiss the trial on the basis it’s unconstitutional to convict a former president on impeachment charges.
