(CNN) Just when you were wondering whatever happened to Jared Kushner, the White House adviser who got his job because his father-in-law is President, he popped up on an Israeli TV station on Monday to jab at the Democrat who may be on the ballot opposing President Donald Trump in 2020. He said he's been busy cleaning up "the messes" that former Vice President Joe Biden was supposedly responsible for creating related to the Middle East and criminal justice.

Kushner's simplistic take sheds little light on the two issues he named, but illumination was not the point. No soundbite could ever help anyone understand the problems he pointed to. Instead, Kushner was obviously trying to distract us from the worsening impeachment crisis that has enveloped the administration, and to impress the Oval Office occupant.

President Trump, who claims to cherish both family and fighting, should take some comfort in the fact that Kushner snarled. The Trumps have made politics, the presidency, and therefore impeachment, into a family affair and so Jared may feel a duty to perform. However, his comments also remind us that the stickiest aspect of the impeachment crisis involves Biden in a way that reflects very negatively on the Trump side.

Remember, it was Biden whom the President sought to undermine when he asked Ukraine's President Volodymyr Zelensky for an official investigation into Biden's son Hunter's work for a Ukrainian natural gas company called Burisma Holdings. Although no evidence of wrongdoing has been offered anywhere, Trump held up nearly $400 million in security aid -- military aid for Ukraine's war against Russia.

Although Trump has said the Zelensky call was "perfect" and involved no extortion or demand of a "quid pro quo," a whistleblower who learned of the communication suspected an abuse of power and raised an alarm. Trump released a rough transcript of the call which plainly showed him seeking dirt on his political rival while the aid to Ukraine was suspended.
