One hour later, Cornyn highlighted legislative efforts targeting illegal immigration. He stated: “While my bill focuses on new criminal and civil penalties for illegal aliens, my colleague, @SenatorBanks, has a Dalilah Law that tackles this issue from the @USDOT angle. Both bills are needed to fix this problem. The Senate MUST pass my bill & @SenatorBanks’ Dalilah Law to” (posted at 20:20 UTC).
In another message posted simultaneously, Cornyn criticized current border policies and referenced recent tragedies: “It is reprehensible that innocent Americans like Dalilah Coleman continue to pay the price for Dems’ dangerous open-border policies, which have led to illegal aliens recklessly operating massive commercial vehicles on our roadways. I am proud to lead my colleagues”.
