e-mail challenged

Things re a little crazy around my job. Good and bad things.
We are receiving a lot of compliments and recognition in the last few months and that is great. So my boss sent this great email to everybody telling them how awesome recognitions we got and that the last one is requiring a trip to receive a prize. Everything was ok to that point. Then, this morning one of our board members replied the email to everyone complaining about the fact that is my boss the one traveling and why can't other board members like himself go as well. There are a few serious problems with this email:
1. The list of email addresses to which he replied included not only board members but also our founders, VIPs from our county and State, and media.
2. He used vocabulary very innapropiate. He referred to our founders as "higher ups" and the officials and people that advocates in our favor as "those with the purse strings".
3. This is not the first time that this exact type of indiscretion happens... with him. Also is not the first time that this type of situation is addressed by the other Board members. All in less than 3 months.

Needless to say, this could hurt us really bad given that we have been working so hard to gain respect from the County and the State and now they all must be thinking that we are nothing but blood suckers and we care more about a free trip and their grants than providing service to our community.
What a shame!
