A Cornell law professor told Tucker Carlson Tuesday that Sen. Elizabeth Warren (D-Mass.) deceptively began to claim Native American heritage to benefit her career as a law professor. 

Warren on Monday published the results of a DNA test as a rebuttal to President Donald Trump, who has long mocked her questionable ancestral claims by referring to her as “Pocahontas.”

While the results indicated Warren may indeed have a trace of Native American heritage – anywhere from 1/64 to 1/1,024 – many Republicans and pundits mocked her for a political miscalculation.

Bill Jacobson, a professor at Cornell Law School and blogger at Legal Insurrection, noted that Warren never claimed Native American ancestry as a child, as a college student or as a law student. 

"She only claimed it when she was in her late 30s and beginning to climb the law professor ladder from the University of Texas to Harvard," he explained. 

Jacobson said Warren was then declared "a minority law professor" and it helped her advance in her law professor career.

"Your viewers need to understand how deceptive Elizabeth Warren was. ... This is a woman who built her political narrative claiming other people are rigging the system. She tried to rig her career by claiming a status to which she's not entitled."

President Trump took to Twitter Tuesday morning to blast Warren, calling her ancestry claims a "scam" and a "fraud."
