In case you missed it, Roberts criticized Trump for the first time by taking issue with the president's labeling of a judge as an "Obama judge".
On Twitter, Yossi Gestetner responded to Schumer, "So Schumer rips the Judiciary as being partisan in the same tweet that he praises Roberts for responding to Trump for criticizing the judiciary as being partisan ..."
During the 2016 election, Trump asserted that U.S. District Court Judge Gonzalo Curiel had an "absolute conflict" of interest and should not preside over class-action lawsuits against Trump involving the dubious Trump University because Curiel is of "Mexican heritage".
As the episodes piled up, from Trump's campaign time in 2016 and into his presidency, the man who sits at the helm of the federal judiciary said nothing.
Mr Trump on Tuesday took aim at US District Judge Jon Tigar in San Francisco, who on Monday temporarily blocked an order by the President that barred asylum for immigrants who enter the country illegally from Mexico.
The court's ruling puts a pin in the president's plan to turn away the approaching migrant caravan.
Trump then told an Army colonel that his troops were getting better equipment than ever before after spending months lambasting the previous administration on military spending, and said to another interlocutor that the nation was doing better than ever in another tribute to his leadership.
The chief justice spoke out broadly about judicial independence in October after the tumultuous Kavanaugh hearings. But Roberts might also have to rule on Trump's fate earlier in the process - if, for example, the Supreme Court has to decide whether Trump must comply with a subpoena from Mueller. From 2010 to 2015, the U.S. Supreme Court overturned 79 percent of the circuit's decisions.More news: Salah denies Egypt coach exit claims: I will win trophies for Liverpool

Roberts was silent during those times when Trump was the target of criticism.
U.S. President Donald Trump started his Thanksgiving holiday by renewed his public debate over the independence of the country's judicial system.
The president repeated the claim that the "9th Circuit is a complete & total disaster", which has been legislating the security of America while not knowing anything about this.
It was Roberts, a nominee of Republican George W. Bush, who was the decisive Supreme Court vote preserving Obama's health care overhaul.
On Wednesday's broadcast of CNN's "Situation Room", Representative John Garamendi (D-CA) discussed the feud between President Trump and Supreme Court Chief Justice John Roberts and stated that "the president is once again seeing himself as a dictator, as above the law, that it's all about him".
Still, this president has been overruled by both Republican- and Democratic-appointed judges.
Trump's response to Roberts' criticism was that there are indeed "Obama judges". "That independent judiciary is something we should all be thankful for", he added in the statement, which did not mention Mr Trump by name.
He even raised the topic during his call to service members, saying the 9th Circuit "has become a big thorn in our side. I would be thinking about how, what is my obligation in this era where this is a president who has more overtly and rhetorically attacked the courts than anyone since the very brief moment where Franklin Roosevelt in 1937 tried to pack the court, and what's my obligation there, and I think he's fulfilling that obligation as he sees it".
