• More than 144,200 migrants were arrested and taken into custody along the southwest border during May, a 32 percent increase from April and the highest monthly total in seven years.

• Faced with the growing possibility of antitrust action and legislation to curb their power, four of the biggest technology companies are amassing an army of lobbyists as they prepare for what could be an epic fight.
