When Yellen responded that Biden "stands ready to work" with lawmakers, Cassidy shot back, "That's a lie because when a bipartisan group of senators has repeatedly requested to meet with him about Social (Security) ... we have not heard anything on our requests."
For several months now, Cassidy and independent Senator Angus King, who caucuses with Democrats, have tried to address Social Security underfunding as approximately 10,000 baby boomers retire every day.
The last week of bank failures and worries of a wider-ranging crisis, however, could give lawmakers second thoughts about investing Social Security funds in stocks.
The senators' effort is not the only Social Security rescue plan being devised.
"That's really just a way to have (benefit) cuts without leaving your fingerprints on it," said Nancy Altman, president of Social Security Works and head of a coalition of labor unions and other liberal-leaning groups.
