California Democrat Eric Swalwell’s troubles deepened on Sunday as the US Department of Homeland Security announced an investigation into allegations the US representative hired “a Brazilian national as a nanny without lawful work authorization”.

Swalwell has been facing a raft of calls to end his campaign for California governor and resign his seat in Congress since Friday, when the San Francisco Chronicle and CNN reported that four women have accused him of sexual misconduct and assault.
