At the California State Capitol, Governor Jerry Brown criticised the new President for his refusal to tether himself to the facts. "Above all else, we have to live in the truth," Brown said.
"When the science is clear or when our own eyes tell us that the seats in this chamber are filled or that the sun is shining, we must say so, not construct some alternate universe of non-facts that we find more pleasing."
Veterans of previous White Houses say they can recall no precedent for what Trump and his top aides are doing.
They worry about the implications of this untethering from the truth when big decisions must be made about dealing with terrorism or charting the course of the economy.
"The degree to which they are creating their own reality, the degree to which they simply make up their own scripts, is striking," said Peter Wehner, a Trump critic who was a top strategist in the George W. Bush White House. "It's a huge deal, because in the end you really can't govern, and you can't persuade people, if you do not have a common basis of fact."
The failure by Trump and his team to maintain discipline will do long-term damage, said Matthew Dowd, who was the chief strategist for George W. Bush's 2004 re-election campaign. "I don't think he realises how much he is hurting himself."
Then again, Trump may well believe that this is the style which brought him to the White House, in defiance of every expectation. Americans knew what they were getting when they elected him.
