Supporters and activists argue that many TPS beneficiaries know no other home than the U.S.
"We need today, for predictability and safety, to know that families will stay together here in the United States," Cardin said.
The bill, which Van Hollen said is cosponsored by another 20 legislators, would offer more than 400,000 people currently under TPS a chance at a green card.
"We think we're in a much better position right now to be able to move forward with the SECURE Act," Cardin said. "We recognize there's going to be challenges. That's why what we're doing here in this news conference is so important. It's to get as much community support as possible to move the SECURE Act."
