Clinton Leads In NY Polls, Sanders Flipping Super-Delegates?, Trump Calls Out RNC Chair

Paul Ryan: 'Count me out'.
House speaker tries to end talk he'll enter presidential race.

House Speaker Paul Ryan on Tuesday tried to end speculation that he may be a late entrant into the Republican presidential race.

"Let me be clear: I do not want, nor will I accept the nomination for our party," Ryan said in remarks from the Republican National Committee's headquarters in Washington.

Ryan, addressing Republican presidential delegates, added: "I believe you should only choose from a person who has actually participated in the primary. Count me out."

Donald Trump rages against the machine.

Donald Trump is issuing a dire warning to his supporters: You're getting ripped off.

"The system, folks, is rigged," Trump told supporters at a rally Monday night in Albany, New York. "It's a rigged, disgusting, dirty system."

Trump is coming to grips with the creeping possibility that he could narrowly lose the Republican nomination at a contested GOP convention despite landing in Cleveland with the most delegates. And his latest comments follow a series of victories by Ted Cruz's well-oiled delegate wrangling machine at state and county Republican conventions, most recently this weekend when the Texas senator swept the Colorado Republican convention -- wins that are fueling Cruz in the event neither of the two men capture the 1,237 delegates needed to avoid a brokered convention.

Zika virus 'scarier than initially thought'

"Everything we look at with this (Zika) virus seems to be a little scarier than we initially thought," Dr. Anne Schuchat, CDC principal deputy director, told reporters during a White House briefing on Monday.


She was joined by Dr. Anthony Fauci, director of the National Institute for Allergy and Infectious Disease at the NIH. "The more and more we learn, the more you get concerned about the scope of what this virus is doing," he said.
