LIV Golf player Patrick Reed’s attorney is already suing five sports media personalities and four companies for defamation.

Now, conservative activist attorney Larry Klayman has threatened to bring similar claims against Bob Costas, CNN, Bloomberg, and others on behalf of the former Masters champ.

Klayman wrote two separate letters this month. In one sent Sunday, Klayman threatened to sue CNN for more than $450 million “if an on air public apology is not immediately made to Mr. Reed,” and “discipline meted out” to Costas and CNN anchor Jake Tapper over a segment on LIV Golf that ran last week.

Klayman also demanded the segment from last Thursday — which Reed wasn’t even mentioned in — be removed from CNN’s website. That letter was addressed to Tapper, Costas, CNN CEO Chris Licht, and CNN attorney David Vigilante.

Klayman gave CNN five days to respond.
