Saw a news report this morning that showed 9,500 containers with
relief supplies for Puerto Rico residents held up in San Juan docks
due to lack of diesel fuel for trucks to haul them to their destinations.

Another 1,500 container ships loaded with supplies are anchored off
the coast, unable to unload due to no room on the docks.

This morning President Trump authorized that the Jones Act be waived
for Puerto Rico, effective immediately.

The Jones act requires that all goods shipped between US ports be
carried by American-owned and -operated ships.

Good we have a POTUS who is staying on top of things.

I just looked and there are a few dozen ships off the coast. I didn't
check each one to see if they are at anchor but I'm thinking you meant
to say 1500 containers on ships at anchor.
