Ladies and gents, boys and girls, we have entered a sort of Twilight Zone of American politics.

No one alive today can remember when the FBI opened an investigation into whether the president of the United States was acting as an agent for a foreign hostile power.

Until now. Allegedly.

The New York Times has reported that the FBI launched such a probe after Donald Trump fired James Comey from his post as FBI director. This is uncharted territory, even for a president who has launched many forays into heretofore unwalked paths.

This is, shall we say, dangerous and frightening in the extreme.

The NY Times reports that the FBI was concerned about Trump’s possible Russia connections even before he fired Comey. Indeed, as a Republican presidential candidate, Trump goaded the Russians into looking for those missing e-mails from Hillary Rodham Clinton, the president’s opponent in 2016. Then the president fired Comey in May 2017 and told NBC News anchor Lester Holt that he fired the FBI boss because of “the Russia thing.”

There now appears to be even more fodder — if you can believe it — for special counsel Robert Mueller to examine possible conspiracy to obstruct justice allegations against the president.

As is his custom, Trump fired off about a dozen Twitter messages this morning condemning what he continues to call “the failing New York Times” and “Lyin’ James Comey,” who he described as a “total sleaze” and a “disgrace.”

Comey is not a sleaze. Mueller is not engaging in a “witch hunt.” Trump himself is acting more like a desperate man looking for political cover.

Count me as one American who wants the Mueller probe to end soon and for him to lay all the facts on the table. Millions of Americans’ inquiring minds want to know the truth about their president.

Something tells me it won’t be pretty.
