Morning Must Reads: September 9

Former Secretary of State Hillary Clinton completed a stunning about-face Tuesday after she declined to apologize for her use of a private email server while in government service. Clinton issued an unambiguous apology in an interview with ABC News after refusing to do so just 24 hours earlier, as her campaign has launched a multimedia assault to make sure her supports hear it. “Yes, I should have used two email addresses, one for personal matters and one for my work at the State Department,” she wrote in a Facebook message and email released late Tuesday. “Not doing so was a mistake. I’m sorry about it, and I take full responsibility.” Clinton still maintains she did not send any information that was classified at the time, an assertion disputed by the inspector general for the intelligence community.

Jeb Bush was a guest on the inaugural edition of The Late Show with Stephen Colbert, where he broke with his brother on government spending and offered the most Jeb Bush-ian answer on why he includes an exclamation point at the end of his name in political ads. “It connotes excitement,” he said. Bush is set to unveil his tax plan Wednesday, relying on cutting loopholes, including the carried interest break beloved by hedge funds, to lower overall tax rates. And Donald Trump and Ted Cruz are set to hold a rally in opposition to the Iran nuclear deal Wednesday in Washington.
