Nope, there wasn't an announcement from either camp; the Times is simply going off of the fact that the Massachusetts senator has a prime-time speaking spot on the first night of the Democratic National Convention.
Giving Warren an extremely visible speaking spot early on is honestly a no-brainer for the Clinton camp. She's been a great Trump-attack dog and is a charismatic darling of the progressive wing of the Democratic party.
Yes, the last two non-incumbent vice presidential picks, Joe Biden and John Edwards, spoke on the third day of the convention. But even the Times' sources concede this doesn't actually mean anything — the speaking schedule isn't set in stone.
The sources also said: "Ms. Warren and other individuals who received invitations on Tuesday to address the Philadelphia convention were told that their speaking times were subject to change depending on who was selected for vice president."
Warren's VP chances probably come down to how badly Clinton needs to attract far-left progressives to her cause. And current general election polls suggest Clinton doesn't have to worry about that just yet; the Real Clear Politics average gives Clinton an almost five point lead over GOP presumptive nominee Donald Trump.

While the likelihood of him agreeing to take on the veep job again might be low, Biden's popularity among Democrats would likely boost Clinton's chances.

Hillary's husband is technically allowed to serve in the job, and some legal experts even think he'd be able to take office if necessary. Unfortunately for the diehard Clinton supporters, a Clinton-Clinton ticket will probably be a dream that never comes true.
