I want you and the people of Israel to know a few things that have not and will not change. The United States stands firmly with Israel, and we have a rock solid commitment to the security of Israel and to the security of its citizens.

My experience is that the director of the FBI is particularly important to just how aggressive an investigation will be into an issue. And once you remove James Comey, it creates a vacuum at the top.
