Bernie Sanders’ campaign is releasing four new TV ads that will air in primary states Tuesday.

Two of the ads feature the Vermont senator and Democratic presidential candidate speaking to crowds: One, titled “Working Families,” shows him talking about the median salary and the “rigged economy.” In another, he vows to “extend the solvency of Social Security and expand benefits for people who desperately need them” if he wins the election. 

A third ad features a nurse who is talking about the high cost of health care and what she says is Sanders’ understanding of the problem. “Bernie Sanders understands how pharmaceutical companies and major medical companies are ripping us off,” she says. “Bernie tells the truth and he’s been consistent.” Sanders supports moving to a single-payer system.

The last ad is a close shot of Sanders discussing a common talking point for him — the uneven distribution of wealth — and his plan to overhaul the economy in favor of working families. “The 15 richest Americans acquired more wealth in two years than the bottom 100 million people combined,” Sanders says.
