Lev Parnas' lawyer puts out a recording of Trump saying "get rid of her, take her out", apparently about the US ambassador to Ukraine, Marie Yovanovitch. (TBF, it's choppy bits of tape, so theoretically could be misleading.)
Trump of course says he doesn't know Parnas, and doesn't know much about Yovanovitch.
I really don't imagine Trump was actually ordering a hit as such. As PP said, not his style to get his hands remotely dirty. OTOH, doubt he'd be upset if his invitation to "rid me of this troublesome priest" had tragic consequences.
