A letter to top defense officials has been sent by two Democratic senators. They are seeking a review of living conditions on certain naval vessels. The ships in question are part of a blockade involving Iran.

The lawmakers' request includes an examination of recent deployments of several ships, including aircraft carriers and a destroyer. One of the ships experienced an engineering failure that left it without power for several days.

Further information about the senators' demands and the situation on the ships can be found through the original report.
