Though former Vice President Joe Biden and his son Hunter weren't the ones on trial in the impeachment proceedings against President Donald Trump, they played a key role in the historic event.

In case you need a refresher, the President was impeached for withholding congressionally approved aid to pressure Ukraine's president to open investigations into the Bidens. Trump later claimed that Hunter Biden's board position with a Ukrainian energy company—and his father's calls to fire the prosecutor investigating the company—amounted to corruption.

Wrongdoing on the part of the Bidens is widely thought to be little more than a conspiracy theory, but with Joe Biden's campaign revived after the Super Tuesday primaries, Republicans are now setting their sights on reviving the investigation as well.

Senator Ron Johnson (R-WI) is seeking to subpoena a potential witness regarding Burisma and the Bidens.

Senator Mitt Romney (R-UT), who was all but exiled from his party after becoming the only Republican who voted to convict President Donald Trump in the impeachment trial, is calling the effort for what it is.

Watch below.

Romney cautioned

"There's no question but that the appearance of looking into Burisma and Hunter Biden appears political, and I think people are tired of these kind of political investigations and would hope that if there's something of significance that needs to be evaluated, that it would be done by perhaps the FBI or some other agency as perhaps a committee of our body."

It's worth noting that the Trump administration expressed no concern in regards to the Bidens and Burisma until Biden announced his candidacy for President, exacerbating the political motivations laid out by Romney.

People respected Romney's consistency.

And they agreed with his assessment that the investigation was politically motivated.

The timing is interesting, to say the least.
