I’ll take all the credit I deserve for this one.

Donald Trump has waived an obsolete and arcane rule that inhibited the free flow of relief supplies to a stricken U.S. territory. The president acted less than a day after an obscure blogger out here in Flyover Country — that would be yours truly — urged him to do so.

He did. Good job, Mr. President.

The Jones Act, enacted in 1920 during the Woodrow Wilson administration, restricts shipping between U.S. ports. It requires ships to be U.S.-owned and that they must comprise crews that are American citizens.

Puerto Rico is in desperate straits. It is without power, potable water, food and other supplies because of the savagery brought to the island by Hurricane Maria. It comprises 3.5 million U.S. citizens who need help — immediately!

The president had signaled an initial reluctance to waive the Jones Act, citing concerns among shipping interests that contended it helps preserve American jobs.

The president, of course, has vowed to “put America first.”

Fine. Then let’s remember that Puerto Ricans are Americans, too. They need the nation’s help. Now. Lifting the Jones Act is a needed boost to a piece of this country in the midst of a serious humanitarian crisis.
