Well, not literally nothing, but close to it.
Senate Majority Leader Mitch McConnell made the announcement yesterday and his short list of objectives includes only one thing they have any chance of accomplishing.
The Senate majority leader said Tuesday that the Senate will take a break for only the first week of August because of "historic obstruction" by Senate Democrats and will stay in session the rest of the month. [...]
"The August recess has been canceled. Senators should expect to remain in session in August to pass legislation, including appropriations bills, and to make additional progress on the president’s nominees," McConnell said.
Confirming Trump's nominees is the only thing they may actually accomplish in August and that's the real reason for McConnell's decision; he wants to confirm more nominees before they lose control of Congress.
Mitch McConnell and the Senate Republicans will not be passing any major legislation or appropriations bills as House Republicans cannot even pass their own bills along party lines and, as of this writing, Speaker Paul Ryan has not canceled their August recess yet.
If you assume there's no chance they will move major legislation, then there's no reason for Ryan to cancel House recess because the House does not confirm nominees.
Given that August is still two months away, and given that there are two more months between August and the November election, you may ask why McConnell would cancel the August recess just to confirm more nominees. The answer is because the entire month of September will be consumed by a mad dash to avoid a government shutdown on October 1st. And after the government is funded, Washington will become a ghost town until after the election if not until January.
Our annual ritual of struggling to avoid a government shutdown at the end of the fiscal year is directly related to the GOP's inability to pass appropriations bills. It's no coincidence that we've talked about a government shutdown at the same time every year since at least 2011 when Republicans first took partial control of Congress.
The Republican party is not a governing party.
