What is my next step after filing a whistleblower complaint?

I recently filed a whistleblower complaint against my VP regarding a couple of situations that happened while we were at a meeting. The first was during a break at the meeting I was getting up to leave the room and he stepped in front of me and pulled out his prescription drugs out his pocket and demanded that I take one. I refused and he continued to demand it until my Sr. Mgr stepped in and asked him what he was doing and why he would be offering someone his pain pills. The next situation occurred later in the day, again at a break, when he got up and jumped in front of me and put his hands together like they were a gun, pointed at my head and said boom. This guy is crazy! Anyway, I filed a complaint with our ethics line and the investigation has taken place - there were several people who witnessed these actions. It appears that nothing is going to happen regarding the complaint as he is still my VP and I am still required to have weekly 1:1 meetings with him. I do not feel comfortable around the guy and I am scared of him. It has definitely created a hostile work environment and it appears the company is pushing it under the rug. I also know that there were at least 2 other ethics complaints against him and those complaints have also been investigated. What is my next step?
