Sen. Sherrod Brown said he backs a proposal from Sen. Kamala Harris to abolish private health insurance.

“I like Kamala,” Brown told MSNBC when asked if he would consider appearing on a ticket alongside Harris in the 2020 elections. “I was amazed at somebody called her un-American today for a proposal she had on health insurance … I stand with her on that, we have stood together on a number of issues, and I think very highly of her.”

Brown, D-Ohio, on Wednesday will launch a tour aimed at promoting a possible White House run in 2020, and has said it should become clear whether he runs in the next few weeks.

Harris, D-Calif., announced last week on Martin Luther King Jr. Day that she was entering the race for the White House in 2020, and kicked off her campaign with a rally in Oakland on Sunday.

A day later, Harris told CNN, “we need to have Medicare for all,” and endorsed the elimination of private health insurance.

"The idea is that everyone gets access to medical care and you don't have to go through the process of going through an insurance company, having them give you approval, going through all the paperwork, all of the delay that may require," Harris said during a CNN town hall Monday night. "Who of all us have not had that situation where you have to wait for approval and the doctor says, 'I don't know if your insurance company is going to cover this.'"

“Let’s eliminate all of that. Let’s move on," she said.

After receiving backlash for proposing a complete elimination of the current healthcare system, Harris walked back a bit on her comments.

Harris’ national press secretary Ian Sams said less than 24 hours after the initial comments that the senator is willing to back healthcare proposals that would not eliminate private health insurance.
