Rep. Alexandria Ocasio-Cortez on Thursday took an apparent shot at Joe Crowley, the former congressman who took job with a high-profile Washington, DC, lobbying firm after she defeated him in a stunning upset in last year’s Democratic primary.

“If you are a member of Congress + leave, you shouldn’t be allowed to turn right around&leverage your service for a lobbyist check,” the on Twitter.

“I don’t think it should be legal at ALL to become a corporate lobbyist if you’ve served in Congress. At minimum there should be a long wait period,” the rookie lawmaker wrote without mentioning Crowley by name.

She linked to a report from , a nonprofit consumer advocacy group, on the revolving door among former lawmakers and lobbyist firms.

The organization’s analysis showed that nearly 60 percent of retired or defeated members of the 115th Congress who have taken jobs outside of government were working with lobbying and consulting firms, or trade and business groups, that do business with the federal government.

The report singled out Crowley, who works for Squire Patton Boggs, and several other ex-lawmakers, including Lamar Smith and Joe Donnelly.

Ocasio-Cortez defeated Crowley, then the No. 4 Democrat in the House, in the Democratic primary election in June 2018.

Crowley didn’t immediately return a request for comment.
