On Wednesday's "CNN Newsroom," Sen. Mark Warner (D-VA) stated that he would be "very reluctant" to end Title 42 until there's a "real plan in place" and that he hasn't heard of a plan like that from the Biden administration. Warner also said he's "very worried" about the prospect "that the border would be overwhelmed," and that "opening the floodgates at the borders would not be the appropriate plan until we have a process to deal with that."
