Newly inaugurated U.S. President Donald Trump is pushing to "take back" the Panama Canal, the world's second busiest interoceanic waterway.

Panama is inching closer to China, Trump's new Federal Maritime Commission head Louis Sola tells CNBC, and 'all options on the table' to defend U.S. business.

President Donald Trump cannot take the Panama Canal — at least not legally — as he would be violating every single treaty that the U.S. has come into with Panama since 1945, international law and national security experts told WLRN.
