Not crimes. If they were crimes, they'd be prosecuted by now. The GOP noise machine calling them crimes doesn't make them crimes. Law enforcement and the judicial system makes those calls, and that's why Trump has been in hot water most of his life.
No, they are collecting evidence now and prosecuting it after eveidence is there. You know, by asking Ukraine to provide it during a phone call, you gibbering loon. As a leftist, I'm not at all surprised you have no clue how justice works.
