As I seek to follow the ongoing impeachment crisis threatening the presidency of Donald Trump, I am getting a sense that the story is getting bigger than many Americans would prefer.

Just three weeks ago we learned about a phone call that Trump had with Ukrainian President Volodormyr Zellenskiy in which he sought a favor from Ukraine in exchange for releasing money to help Ukrainians fight Russian aggressors.

The phone call prompted House Speaker Nancy Pelosi to launch an impeachment inquiry. The thought as I understood at the time was that the House would move rapidly toward an impeachment vote by Thanksgiving. It would be a narrowly focused matter: whether the president violated his oath by seeking foreign government help in his re-election and seeking foreign help in digging up dirt on Joe Biden, a potential foe in the 2020 presidential election.

Now it seems as if this story is getting many more tentacles.

Trump appeared to suggest that the vice president, Mike Pence, had conversations with Ukrainians as well; Secretary of State Mike Pompeo at first denied knowledge of the Trump-Zellenskiy phone conversation, then acknowledged he was “on the call”; questions have now arisen about Turkey and whether the president’s decision to abandon our allies in Kurdistan in the fight against ISIS is somehow related to a Trump Towers deal in Istanbul.

My head is spinning, man.

Does all of this come together quickly? Can there be an impeachment vote by Thanksgiving? Can the Senate commence a trial and make a decision by, say, spring 2020? Is all of this getting so muddy that we won’t have a resolution until after the 2020 presidential election?

As if it needed to get more complicated. The juxtaposition of a re-election fight and an impeachment muddies matters beyond anything the nation has experienced. President Clinton was a lame-duck second-term president when the House impeached him in 1998; President Nixon was in the same boat when the House Judiciary Committee approved articles of impeachment in 1974. Neither man faced re-election.

This whole scenario is vastly different. Moreover, it keeps growing in its complexity as more Cabinet officials get sucked into the debate over what they knew and when they knew it.

I need something to settle my nerves.

I also want this saga to end — either through impeachment and Senate conviction, or at the ballot box — with Donald Trump vacating the Oval Office for a final time.
