As lawmakers work to avoid another partial government shutdown, Sen. Elizabeth Warren is keeping up pressure on big banks to make sure they help federal employees and contractors, especially if the “agreement in principle” falls apart.

“We are now less than a week away from the February 15 deadline to fund the government, and President Trump has threatened to drag the American public through a shutdown for a second time,” the Democrat from Massachusetts wrote in a series of new letters shared first with Roll Call.

Several weeks into the last shutdown, Warren sent letters to some of the nation’s largest financial institutions asking what sort of assistance they were providing to workers who were furloughed or working without pay.

And now the banks — Bank of America, Citigroup, JPMorgan Chase, U.S. Bancorp and Wells Fargo — have all responded to the senator and 2020 presidential hopeful. In the reply letters, the banks outline what they ultimately did to help their customers.

The responses, which were also reviewed by Roll Call, show that the banks generally treated government shutdowns as they would a natural disaster.
