Monday, after spending the weekend using social media to reignite his gratuitous fight with the mayor of London over terror attacks, he took to Twitter to severely damage the legal defense for his executive order banning travel to the USA from six majority-Muslim countries.
In a series of Monday morning tweets, Trump says the Justice Department "should have stayed" with his first executive order aimed at temporarily halting entry to the USA from a half-dozen Muslim majority countries.
Trump was referring to his controversial original travel ban, which barred the entry of citizens of seven Muslim-majority countries to the United States, but was quickly fired down in several federal courts shortly after its disastrous implementation.
The Justice Department filed two emergency applications with the Supreme Court last week to have the ban reinstated.
House Minority Leader Nancy Pelosi has accused President Donald Trump of disregarding the Constitution following a series of tweets in which he defended his travel ban. "The courts are slow and political!" he said in another.
4 nations cut diplomatic ties to Qatar as Gulf rift deepens
A fourth country, the United Arab Emirates, echoed the same accusations and accused Qatar of was undermining regional stability. Saudi Arabia cut all land air and sea contacts with Qatar 'and urges all brotherly countries and companies to do the same'.
In a rare move on Friday the Supreme Court expedited consideration of the case, ordering the American Civil Liberties Union-which represents the plaintiffs-to respond by June 12 to the Trump administration's petition for court consideration.
"We will keep it free and keep it safe, as the media knows, but refuses to say".
The first version of the ban was blocked by the courts, whereupon the administration issued a revised version of it on March 6 that is now under review by the Supreme Court.
Trump has presented the measure, which seeks to halt entry to the USA for 90 days for people from several predominantly Muslim countries and bar refugees for four months, as essential to prevent attacks in the US.
Spicer has also made it a habit of saying "The president's tweets speak for themselves".
"It's kinda odd to have the defendant in Hawaii v Trump acting as our co-counsel".
We need to be smart, vigilant and tough. "I am calling it what we need and what it is, a TRAVEL BAN!"
But the president's next tweet contradicts to what Sanders said. Trump has already seen his past statements, and those of his surrogates, used against him in court, particularly his calling for a Muslim ban in December of 2015. Trump tweeted in one Monday morning.
