McCain's comments come as many 2020 presidential candidates voice outrage over a social media post that falsely claimed the California senator, who is of Indian and Jamaican descent, is not black.

“Is this true? Wow,” Trump Jr. tweeted to his 3.65 million followers before deleting it.

"This is the same type of racist attack his father used to attack Barack Obama," Harris spokeswoman Lily Adams told CNN. "It didn't work then and it won't work now."
A spokesman for Trump Jr. told The New York Times that his post was a misunderstanding.
“Don’s tweet was simply him asking if it was true that Kamala Harris was half-Indian because it’s not something he had ever heard before,” said spokesman Andy Surabian, “and once he saw that folks were misconstruing the intent of his tweet, he quickly deleted it.”
President Trump helped promote the conspiracy theory that questioned whether Obama was born in the United States.

McCain, a daytime talk show host, has repeatedly criticized Trump during his time in office.
She said in late May that Trump was a "child" who will always be "deeply threatened" by her father following a report that the White House wanted the USS John S. McCain "out of sight" during the president's visit to Japan.
