kicked out of school

Thomas Jefferson is a Joke... The principal has disliked Bruna from day one!! The first day he spoke spanish with her, which she speaks Portuguese.... She answers in English and he gets frustrated cause he wants her to respond in Spanish. A few days after this started she finally told him that in Brazil that they speak Portuguese.....he assisted to argue with her and she told him to google it....He was mad that she stood up to him....
Also, there are close to 12 foreign exchange at this school.... They all hug good bye.. Mr...Jerk, the principal, watched Bruna very closely. He wants her back in Brazil. He also has a foreign exchange student that is a boy and when Bruna does her rounds of hugs, she hugged him and The principal went to her yelling at her that they were making out and groping each other. He called me last Wednesday saying that she needed consequences for her actions. After talking with her she told me that they never do anything like that except hug goodbye. I told her that I would talk to him on Tuesday when they resumed back to school.
So I called the school on Tuesday and asked for an appt. Cathy, the sec, said there was nothing till Thursday. So I said ok. About 15 minutes later she calls back and says to pick up Bruna NOW and The principal wanted to meet with me.... ASAP....So about 20 minutes later I got the the school and Mr. Jerk and I went into the office and he yelled at me for about 45 minutes...Saying Bruna was selfish, spoiled and strong minded...
His first issue he brought up that He and the boy were to close and she was laying on his P@nis...over and over again... For a principal he could have used lap or genitals....
second issue was Bruna is late to school and to class everyday. She rides the bus so I know this is not true... I asked if I could speak to the teachers about her attendance and her attitude and performance, He said NO.... I told him that we have friends come to the house and I do ask about Bruna's performance to the friends and he said to me " I see where your maturity level is." That irritated me...
He told us that she was not able to come back till her attitude changed and she could follow all rules and bend over backwards. She must be in school because the semester started or she must go back to Brazil... So there is no choice to allow her to take a break from him!!
After we left, he told our coordinator that he admitted to judging me for my age but I did very well as he was criticizing me....
We are working on getting her to a different school but until we can she must be on her best behavior and do everything to a T..including an apology letter to him....She took this to him yesterday and he replied that it was exactly what he wanted....JERK!!!
She is in good spirit about this and I can not wait till we can get her out of there!! We are going to the Board about this situation!!

I hope your day is great and if you have any ideas let me know!!
