Harris unveiled some economic policies, including a ban on price-gouging, which has been criticized by opponents as similar to price controls, and has said she would defend abortion and support families, without going into intense detail. Booker pushed back on claims she has not elaborated policy on CNN’s State of the Union on Sunday.

“She released a pretty specific, detailed plan on a lot of her economic agenda. Whether it’s about trying to do specific things, like with tax credits and more to create more housing, and to help to create more supply and thus lower the cost of housing she created,” Booker said, discussing the ban on price-gouging proposal.

Booker also pointed to Harris’s claim that she would sign into law a bill that claims to revert federal abortion law to Roe v. Wade, rather than leave the matter to the states.

“So, from reproductive rights to lowering costs, she’s been very specific. And as this campaign goes on, she’ll be sitting for more interviews; she’ll be engaging in debates — I think she wants to do more if Donald Trump will actually show up to a debate,” Booker said.

Harris has yet to have a sit-down interview with a media outlet since she entered the race more than a month ago, but has vowed to do one. The vice president and former President Donald Trump will debate on Sept. 10, in a debate hosted by ABC News.

Trump has pushed for multiple additional debates, but the Harris campaign has said it would be open to an additional presidential debate in October. Trump’s running mate, Sen. J.D. Vance (R-OH), and Harris’s running mate, Gov. Tim Walz (D-MN), have agreed to a vice presidential debate on Oct. 1, hosted by CBS News.

As the campaign continues, Harris is expected to face pressure on explaining more of her campaign’s policies on other matters outside of price gouging.
