Paul Manafort is under house arrest after being indicted for money laundering and conspiracy in connection with Donald J. Trump’s presidential campaign.

The former Trump campaign chairman, though, reportedly has engaged in some seriously weird travel behavior.

Court filings have revealed that Manafort has three U.S. passports, all under different names. He reportedly traveled abroad under aliases.

It makes me wonder: Who in the world does that?

I get that Manafort is a wealthy man, as Rick Gates, a campaign deputy who also has been indicted by the grand jury impaneled by special counsel Robert Mueller, who is investigating that so-called “Russia thing.” I also get that rich people do things with which I am unfamiliar.

For instance, I possess just one passport. It has my actual name, my actual date of birth and my actual statement that I am an American citizen. I present it when I travel abroad. Passport officials look at it, stamp it and send me on my way.

Financial holdings also questioned

CNN reports as well that Manafort revealed differing estimates of his net worth, as did Gates.

Both men have pleaded not guilty to the assorted money laundering and conspiracy charges. They now are entitled to mount vigorous defenses to uphold their not-guilty pleas.

I have to wonder, however: What in the world gives with the multiple passports and fake names?
