The only real question remaining about Hillary Clinton's forthcoming presidential campaign is when the former secretary of state will formally announce it.
By signing an April lease on office space in Brooklyn, Clinton effectively started a 15-day countdown on the day when she would publicly declare herself in the running, as FEC rules state that candidates have that amount of time in which to conduct campaign activities before filing official paperwork.
Late Thursday, the New York Daily News ran a story that cited an anonymous source who claimed that Clinton was planning to formally enter the presidential race on Sunday. While several news outlets ran with that reporting, the Clinton campaign refused to confirm it and later reports from The Guardian and NBC News with similar information.
The Guardian also added that Clinton's plans included kicking off her candidacy on Sunday at noon with a tweet to her 3.12 million followers. Then, according to the Guardian, she would lead a "blitzkrieg tour" starting in Iowa, followed by other early primary states.
Unlike Texas Senator Ted Cruz, Kentucky Senator Rand Paul both of whom released venue details ahead of their well-attended campaign roll-outs, Clinton has given no such clues, keeping campaign-watchers glued to her Twitter feed for clues. Florida Senator Marco Rubio, by contrast, has all but stated he will declare his own entrance in the race on Monday at an event in Miami.
