For Harvard law professor Laurence Tribe, not only do Donald “Trump's "jokes" about Russia amount to "inviting an adversary to wage cyberwar against the U.S.," but they also "appear to violate the Logan Act and might even constitute treason,” he tweeted Thursday.

The latest tweet from the liberal legal giant whose name has been floated as a Supreme Court pick comes after Trump and his campaign brushed aside the backlash over his remark. The Republican nominee himself telling Fox News that he was "being sarcastic."

“Imagine what our 1st president would've said about a candidate inviting a foreign power to intrude into a US election for the 45th president,” Tribe previously tweeted Wednesday, adding that he “must have been hallucinating” at hearing Trump’s calls for Russian hackers to infiltrate Democratic presidential nominee Hillary Clinton’s emails.

He also wrote, "I've been saying the Russian hacking into DNC is Watergate on e-steroids."

Though a former Obama mentor, Tribe also buttressed Trump’s charge against former Republican presidential candidate Ted Cruz, one of his other former law students, over his citizenship and eligibility to serve as president.

He told The Guardian in January that according to the “originalist” judges Cruz so adored, “Cruz wouldn’t be eligible because the legal principles that prevailed in the 1780s and 90s required that someone be born on US soil to be a ‘natural born’ citizen.” Tribe subsequently penned an op-ed titled “Under Ted Cruz’s own logic, he’s ineligible for the White House” in the Boston Globe.
