Bolton is militantly anti-Russian. Thus, Bolton would oppose any delay in providing aid to the Ukraine.
But Bolton would be well aware of Trump's concern for Ukrainian corruption. He would also be well aware that the aid was not held-up for some personal gain.
Bolton is NOT going to support the fairy tale that the democrats have created. This favors the President a little.
Bolton would be dead to conservatives and Republicans were he to work with the Democrats. The DIMS already hate him so if he comes off anti-Trump, his book and he will relegated to the appropriate dustbin of history. He would be lucky to sell 100 copies.
However, after the impeachment is over and he release a "bombshell” tell all book critical of the inner workings of the Trump Administration, he will be on every talk show from now until election day.
Trump is not worried about Bolton so I am am thinking Bolton will have very little to offer with regards to Ukraine. He hates Ruddy and that is where his venom will be directed if he were to testify.
I am beginning to wonder if there is not some link between the Biden’s and Ukraine's involvement in the Steele Dossier?
