[T]he idea that sitting presidents always accord deference to the judiciary is not historically accurate.
From Thomas Jefferson to Barack Obama, U.S. presidents have lashed out at the judiciary in general and the Supreme Court in particular, and in ways far more threatening than a couple of insulting tweets.
[W]hen it comes to Donald Trump, his critics have selective memories, along with a clear double standard. Where was the outrage in liberal quarters when Barack Obama went on a sustained public relations campaign to intimidate the Supreme Court into upholding the Affordable Care Act? Or when he publicly assailed the court for upholding the First Amendment in the Citizens United case?
In his 2010 State of the Union Address, with several of the justices sitting in front of him, Obama delivered a blistering attack on Citizens United, which he said “reversed a century of law to open the floodgates for special interests — including foreign corporations — to spend without limit in our elections.”
