Obama's bill does not tie a pathway to citizenship for illegal immigrants to new border security measures and does not create a new visa exit system — two provisions Republicans have insisted on in negotiations. In a statement, Rubio described the plan as "dead on arrival."

"I've said repeatedly that I want Congress to go ahead and negotiate and get a bill done. But what I've also said is we're preparing a bill so that if Congress doesn't do its job, we're going to go ahead and put a bill on the floor of the United States Senate," Obama said.
Obama's calls on Tuesday appeared to smooth the waters with negotiators across the aisle, with spokesmen for the Republican senators issuing optimistic statements following the conversations.
