There has been no formal adoption of C.E. in the United States. There is no law that requires the use of CE (Common Era) and the issue has not been brought before the Supreme Court.
You have highlighted an interesting issue. The use of A.D. (Anno Domini- year of our lord) gives privilege to Christianity even though it is no longer the defining belief system. It refers to Jesus and Jesus is not the universal lord. That term is not used in many cultures and is being dropped from academic publications and many popular publications. The terms B.C.E. (Before Common Era) and C.E. (Common Era) are religiously neutral.
If you object to the use of the term by a public official you should consider making a formal written complaint informing them of the religiously neutral term. You could take the issue to your local newspaper perhaps by a letter to the editor.
