1 - Nobody is suggesting that Congress suspend the Prez's pay. Just not cut the check until there is money in the checking account again.
2 - Suspending the actual paychecks of military is going to cause massive headaches. Many "junior ranks" are like the rest of the population, living from paycheck to paycheck. Even with administrative leave granted to get into town to apply for SNAP (Supplemental Assistance for Needy Persons) (aka Food Stamps) the welfare dept. offices may be closed because of a failure of federal funds to flow through to the states to pay the folks who process the applications.

Life sucks bad enough for military dependents who are moved out of base housing because their sponsoring service member is on overseas deployment.
