3. Plan to Privatize U.S. Air-Traffic Control Revealed

President Trump has unveiled a new plan to privatize the U.S. air-traffic control system, reports Skift. The proposal, designed to lower costs and improve efficiency of the system that oversees flights, would transfer about 15,000 controllers and thousands of other managers and technical workers to a new government-sanctioned corporation. The plan is part of the White House's stated goal to spur investment in U.S. infrastructure. Critics of the air-traffic plan have said it would jeopardize small airports by giving too much power to airlines and large hubs.

4. Appeals Court Upholds Block of Travel Ban

The U.S. Court of Appeals' Ninth Circuit in San Francisco has ruled that President Trump's executive order limiting the ability of travelers from predominately Muslim countries to visit the U.S. will remained block, reports Skift. The ruling focused particularly on limits placed on the entry of refugees and the 90-day ban on admitting new visitors from select countries. "We conclude that the President, in issuing the Executive Order, exceeded the scope of the authority delegated to him by Congress," reads the opinion. "In suspending the entry of more than 180 million nationals from six countries, suspending the entry of all refugees, and reducing the cap on the admission of refugees from 110,000 to 50,000 for the 2017 fiscal year, the President did not meet the essential precondition to exercising his delegated authority: The President must make a sufficient finding that the entry of these classes of people would be 'detrimental to the interests of the United States.'"
