If this evidence holds up, the Democrats are likely to start the impeachment process but I doubt the Republican controlled Senate would convict him. That said, I think the national attention the impeachment process would provide would hurt Trump. If this manages to damage his approval ratings with Republicans, while they still might not convict him, but I could see Republicans backing away from Trump in order not to be brought down with him. Which would in turn hurt and slow down his agenda.
That said, with the craziness that the Trump administration has brought, it could easily go a different way.
