CNN cut ties with Jeffrey Lord - here are some of his most controversial moments

CNN cut ties with Jeffrey Lord on Thursday after the right-wing commentator tweeted a Nazi slogan at a liberal activist.

"Nazi salutes are indefensible," a CNN representative said in a statement after Lord tweeted "Sieg Heil," the Nazi victory salute, at Media Matters president Angelo Carusone. "Jeffrey Lord is no longer with the network."

The tweet was far from Lord's first brush with controversy since his ascent to the national stage during the 2016 presidential campaign. As one of CNN's few steadfast Donald Trump supporters, Lord was at the center of some of the cable network's most shocking moments over the last year.

During the primary season, he rankled CNN commentator Van Jones by calling the Ku Klux Klan a "leftist" organization after members of the white-nationalist group endorsed Trump for president.

There was the time in November when he asked a black panelist when he would apologize for slavery.

There was the time in October when he attempted to downplay Trump's "bad hombres" comment at a debate by saying it wasn't as bad as the N-word.

More recently, in April, Lord brought a CNN panel to a standstill when he called Trump "the Martin Luther King of healthcare."

After CNN cut ties with Lord, Fox News, NBC, and MSNBC all announced they would not be hiring him. He remains a columnist for the right-wing magazine The American Spectator.
