The only viable one is flipping Murkowsky or Collins. Lets see if we can also flip some Dems in red states like manchin. As for the one about trump being under investigation and therefore limited in his ability to appoint a justice, Clinton already did that when he had an IG looking at him, so not only is there no basis in law for it, but the article omits that there is precedent against it.
Not an IG, but rather a Special Prosecutor.
Janet Reno appointed Robert B. Fiske as special prosecutor to the Whitewater Controversy In January 1994.
Bill Clinton appointed Stephen Breyer to the Supreme Court in April 1994 and he was confirmed by the Senate in July.
In August, Ken Star took over the Whitewater investigation from Fiske.
