Warren says (4 times) she's not running for president

She's said it once, and she'll say it four times: Sen. Elizabeth Warren is not running for president.
Asked four times by NPR's Steve Inskeep on Monday morning whether she was running for president, Warren held her ground, repeating each time: "I am not running for president."
"That's not what we're doing. We had a really important fight in the United States Congress just this past week, and I'm putting all my energy into that fight, into what happens after this," the Massachusetts Democrat said.
Inskeep pointed out that she was speaking in the present tense, and that she hadn't said she would "never" run, but Warren didn't change her tune, eventually becoming so exasperated she demanded, "do you want me to put an exclamation point at the end?"
