Progressives upset Kamala Harris is campaigning with Liz Cheney: Report

Some progressive Democrats have expressed concern over Vice President Kamala Harris' decision to campaign with Liz Cheney, suggesting she focus on her Democratic base.

Hanna Panreck is an associate editor at Fox News.

Cheney, an anti-Trump Republican, has appeared on the campaign trail with Harris several times. Other progressive leaders, such as Sanders or Rep. Alexandria Ocasio-Cortez, have been "relegated to low-profile roles," according to the AP. 

"She has to start talking more to the needs of working-class people," Sanders told the AP. "I wish this had taken place two months ago. It is what it is."
