In the aftermath of the London terror attack, Trump retorted once again to the U.S. courts for blocking his attempted travel ban against people from six Muslim-majority countries.
It's hard to say what impact the president's words - and tweets - will have on any decision by the high court, but he vented his frustrations against the courts calling them in tweets "slow and political".
The American Civil Liberties Union said on Twitter that they "may incorporate" Trump's tweets on the ban "into our Supreme Court argument".
"It's kinda odd to have the defendant in Hawaii vs Trump acting as our co-counsel". We do not need the travel ban, studies have shown that there's been no terrorist attacks carried out in the United States by any of the countries listed in the ban.
The lower courts have cited Trump's own statements, primarily on the campaign trail a year ago, that the order should be seen as a "total and complete shutdown of Muslims entering the United States" to reject the ban. Earlier Monday, Trump called it a "watered down Travel Ban."
However, on Monday, Trump's statements undercut his own administration's contention that the executive order is not a "travel ban," as Trump himself insisted on using that phrase.
Whether Trump's statements during the campaign - calling for a surely unconstitutional blanket ban on Muslim visitors from anywhere - should be taken into account by courts considering the current "watered down" version is debatable.
Deputy White House press secretary Sarah Huckabee Sanders on Monday said the administration feels the order should simply be framed as a national security measure.
"We want to ensure that we are not admitting into our country the very threats our soldiers are fighting overseas", Trump said at the time.
After weeks of conflicting messages from White House officials and federal attorneys over whether President Donald Trump's so-called travel ban is a travel ban, the president answered that definitively on Monday, and in so doing raised a new question: Could his tweets about why he wants a travel ban imposed on six Muslim-majority countries hurt his effort to reinstate the travel ban that's been repeatedly blocked by the courts?
"Sad", he said on Twitter, borrowing a phrase from Trump's own Twitter.
President Trump has previously used the phrase "watered down" to describe his revised executive order. "In any event, we are EXTREME VETTING people coming into the U.S.in order to keep our country safe". The narrower order temporarily halts entry to the US from Iran, Libya, Somalia, Sudan, Syria and Yemen is necessary to protect USA national security.
"The President's tweets may help encourage his base, but they can't help him in court", Case Western Reserve University Law School professor Jonathan Adler said in a Reuters interview.
