This is correct. And if/when the articles are presented, McConnell has the sole power to DENY them. To return them and the Managers back to the House. No votes needed. No hearings, no nothing.
While that is a viable option, it would deny the President’s team from getting their message out. It would also miss the opportunity to expose the corruption of the Bidens and the true scale of the deep state attempt to overturn the election.
I am of the opinion that is why Nancy is slow rolling the articles. She KNOW that if the Senate (where she has no control) begins to investigate the whole Russia hoax, the Dems will be exposed and will likely loose control of the House in the election due to voter backlash.
