Sen. Kamala Harris (D-Calif.) reportedly said she is “deeply” concerned by comments former Vice President Joe Biden, her competitor in the 2020 primary, made regarding working with segregationist senators. 

“Yes, it concerns me deeply. If those men had their way, I wouldn’t be in the United States Senate and on this elevator right now,” Harris said Wednesday, according to tweets from several reporters.

Biden came under fire after he cited his working relationships with two segregationist senators in the 1970s as an example of a bygone era of “civility” in the Senate.

Biden said he didn’t “agree on much” with former Sens. James Eastland (D-Miss.) and Herman Talmadge (D-Ga.) but that they “got things done.”

Eastland blocked more than 100 civil rights-related bills during his time as Senate Judiciary Committee chairman.

Biden, who is making his third attempt for the White House in 2020, faces a crowded field of younger, more diverse candidates and many who are to his left.

His comments were also condemned by Democratic primary challengers New York City Mayor Bill de Blasio, Sen. Elizabeth Warren (Mass.), Sen. Cory Booker (N.J.) and former Rep. John Delaney (Md.)

Biden sits at the top of the field in most polls, but his support has dipped since he launched a few months ago.

The Hill has reached out to Harris’s office for comment.
