Squib_Kick: Tribe is a an extreme leftie Never Trumper from the beginning.
From wikipedia:
Tribe served as a judicial adviser to the Barack Obama's 2008 presidential campaign. In February 2010, he was named "Senior Counselor for Access to Justice" in the Department of Justice. He resigned eight months later, citing health reasons.
In December 2016, Tribe and notable lawyers Lawrence Lessig and Andrew Dhuey established The Electors Trust under the aegis of Equal Citizens to provide pro bono legal counsel as well as a secure communications platform for those of the 538 members of the United States Electoral College who were considering a vote of conscience against Donald Trump in the presidential election.
After the dismissal of James Comey in May 2017, Tribe wrote: "The time has come for Congress to launch an impeachment investigation of President Trump for obstruction of justice." Tribe argued that Trump's conduct rose to the level of "high crimes and misdemeanors" that are impeachable offenses under the Constitution. He added: "It will require serious commitment to constitutional principle, and courageous willingness to put devotion to the national interest above self-interest and party loyalty, for a Congress of the president's own party to initiate an impeachment inquiry."
Tribe on the board of the Renew Democracy Initiative, an American political organization founded in 2017 to promote and defend liberal democracy in the U.S. and abroad.
In 2004, Tribe acknowledged having improperly borrowed without attribution several phrases and a sentence in his 1985 book, God Save this Honorable Court, from a 1974 book by Henry Abraham. After an investigation, Tribe was reprimanded by Harvard for "a significant lapse in proper academic practice," but the investigation concluded that Tribe did not intend to plagiarize.
Tribe has stirred controversy due to his promotion of reliable claims about President Trump's fitness for office. Dartmouth political scientist Brendan Nyhan harshly criticized Tribe, saying that he "has become an important vector of misinformation and conspiracy theories on Twitter." According to McKay Coppins of The Atlantic, Tribe has been "an especially active booster" of the Palmer Report, "a liberal blog known for peddling conspiracy theories". Tribe removed the posted tweets following the Palmer Report and contests the accuracy of the story of controversy.
Controversially, Tribe has promoted unreliable sources and conspiracy theories about Donald Trump.
