For a political newcomer whom even some Democratic pundits think of as a "self-perpetuating legend" unworthy of the "hype," Alexandria Ocasio-Cortez is proving to be quite good at her job—and not just, as her critics contend, at Twitter. During Michael Cohen's testimony in front of the House Oversight and Reform Committee on Wednesday, the congresswoman cleverly helped lay the groundwork for a potentially wide-ranging investigation into the president's well-documented but still not fully understood history of financial wrongdoing and criminality.

She didn't even need all five of her allotted minutes. In about four minutes and 17 seconds, Ocasio-Cortez cruised through a rapid-fire questioning of Donald Trump's former attorney and fixer, homing in on the goods.

First, Ocasio-Cortez delved into the infamous "treasure trove" of stories stockpiled by AMI, the National Enquirer's parent company. They were part of a catch-and-kill operation designed by Cohen and AMI to shield the president from future embarrassing Stormy Daniels–esque revelations. When Cohen replied that he could no longer be sure of the whereabouts of these documents, Ocasio-Cortez—instead of pressing him for lurid details about their contents—simply asked who might be able to tell the House Oversight Committee more about them. Cohen, under oath, named names: David Pecker, Barry Levine, and Dylan Howard.

Pecker, who is AMI's chairman and CEO, already struck an immunity deal with federal prosecutors in conjunction with his involvement in hush-money payments during the 2016 campaign. But this agreement would not preclude Pecker (or Levine or Howard) from testifying about the matter before Congress, whether on a voluntary basis or pursuant to a subpoena. Should committee chair Elijah Cummings elect to exercise this power in the near future, the responses Ocasio-Cortez elicited provide him with ample justification for doing so.

Next, she turned to a pair of strategies that Trump purportedly employed before ascending to the White House in an effort to preserve his wealth: inflating the value of his assets when dealing with insurance companies, in order to obtain favorable coverage terms, and then deflating the value of his assets when dealing with local government officials, in order to reduce his property-tax liability. Cohen confirmed his general familiarity with these practices, but also disclosed the limits of his knowledge; he couldn't, for example, speak directly to alleged shell-game maneuvers that took place in the 1990s, before his tenure with the Trump Organization began.
