MORE E-MAILS TO COME? The State Department is asking Democratic presidential candidate Hillary Rodham Clinton to affirm that all federal records in her possession have been handed over, including work e-mails sent on her private account while she was secretary of state. “The Obama administration recently discovered a chain of 2009 e-mails between Clinton and former Army Gen. David Petraeus that were not included among the 55,000 pages she had handed over,” the Associated Press reports. “Their existence challenges the Democratic presidential front-runner’s claim that she has already provided all of her work e-mails from her tenure as secretary, which are the subject of several public records lawsuits.”

RUBIO UNVEILS TAX REFORM: Sen. Marco Rubio (R-Fla.) said his proposals to reform the tax code would help companies like Uber and Airbnb flourish. “‘The on-demand economy is a miracle that only American free enterprise could produce,’ he said, according to the text of his remarks delivered at Civic Hall in New York,” the Hill reports. “‘That’s why it’s so shameful that the biggest obstacle to the growth of this platform is our very own government.’ He said that in the on-demand economy, ‘innovative companies are running up against an antiquated tax code, burdensome regulations, and numerous outdated politicians.'”

MORE DISAGREEMENTS ON CYBERSECURITY BILL: The Senate’s cybersecurity bill is still in limbo given a packed legislative schedule. “The bill’s sponsor, Senate Intelligence Committee Chairman Richard Burr (R-N.C.), and the Intelligence ranking member Sen. Dianne Feinstein (D-Calif.) said Tuesday they expect the legislation to return to the floor when the Senate returns from recess in a few weeks,” the Morning Consult reports. “But the Senate still has plenty of work to complete on a pile of appropriations bills, budget reconciliation, and highway funding. Other duties notwithstanding, Senate Majority Leader Mitch McConnell (R-Ky.) might be unwilling to bring up the measure without assurance the bill won’t eat up lots of floor time.”
