Speaker Nancy Pelosi (D-Calif.) on Sunday said holding up a COVID-19 relief bill as a way to demand a vote on Title 42, a Trump-era pandemic public health policy that allows for the rapid expulsion of migrants at the border and prevents them from seeking asylum, is “blackmail,” but she appeared open to the notion of Congress holding a vote on the controversial measure.

The comments came after Senate Republicans in early April blocked the upper chamber from advancing a $10 billion COVID-19 bill after Democrats refused to vote on an amendment that called for blocking the Biden administration from rescinding Title 42.

An increasing number of Senate Democrats, however, are becoming more open to holding a vote on the controversial policy. Sen. Chris Murphy (D-Conn.) last week said “there’s a growing willingness to bring that up and have the amendment votes necessary to get it to a final vote.”
