President Trump planned to have dinner with the justices of the Supreme Court on Thursday evening, but the White House said Sunday evening the event will take place on a future date because of scheduling conflicts. 

Newly confirmed Justice Neil Gorsuch was slated to attend, but it was not clear which of the eight other justices might be present. 

Trump’s successful nomination of Gorsuch to the court is seen as a key accomplishment of his first 100 days in office, as he made good on a major promise of his campaign to fill the vacant seat left by the death of Justice Antonin Scalia.

{mosads}Presidents hosting Supreme Court justices for dinner isn’t unusual.

Presidents Hayes, Franklin D. Roosevelt, Eisenhower and Carter all hosted members of the court at the White House. More recently, President George W. Bush and his wife hosted members of the court for a dinner in 2008. 

On social media, Sen. Brian Schatz (D-Hawaii) questioned the arrangement before the cancelation was widely announced. 

Why would the Supreme Court agree to do this? I can think of no legitimate reason to dine with a litigant. https://t.co/tcjQ6vzYv6
