The Senate voted on Monday to accept stronger border security measures, setting up a successful vote on a bill to reform the country's immigration laws. Lawmakers voted 67 to 27 to prevent a filibuster of the plan, which would allocate roughly $30 billion for border enforcement and called for doubling Border Patrol personnel to 40,000 agents. It would also require the completion of 700 miles of fencing. Those lawmakers opposing the plan said it should require that the border be secure before the 11 million undocumented immigrants already in the country could seek citizenship.
