Hello, its always better to give a try, but DoS has been paying little (infact No) heed to senators, congresspersons requests. If you have a compelling case, you can try requesting expedite on your own to save senator's routing time. DoS is pretty fast in deciding whether to approve or disprove expedite request. Even if it approves, it takes some time depending upon if you have government funding or not, as sponsors take 1-4 months in responding back to DoS. Good luck!
