Hi, Mike Powell!
I read your message from 17.03.2018 01:59

 MP> "... it had ordered Thursday that the cables be tightened..."
 MP> "... it had ordered Thursday for the cables to be tightened..."

 MP> I believe that "be" is correct when using
"that," while "to be" would be
 MP> correct when using "for."

 MP> I could also be very wrong. :)

If we don't use the Infinitive for making the future tense I also have a
vague doubt that we have here a reported speech, and the original sentence
should have been like this:

....it had ordered Thursday that the cables were tightened...

(...Mr. Rubio, a Republican, said in a late Thursday tweet...)

Bye, Mike!
