They needed a distraction. Biden was/ is taking a beating and running up to the midterms, they need to try take biden's agenda out of the equation.
I expect this will be a very hot summer down there. Government is about to shut down for the summer and many important matters will just be left on the table. Sure as god made little green apples, some white cop is going to shoot a black guy and cue BLM and ANTIFA. Looting, burning, killing will occupy the airwaves with each side blaming the other. When they return, it'll all be about the midterms. After November, they have a lame duck system until January, when the new blood gets sworn in. If the dems win, expect biden to triple down (if he is still president) if the GOP win, I expect a number of impeachment trials, passing legislation to complete the wall and shut down the southern border. With luck, they'll have a large enough majority, that they can veto an executive order.
