The Orange County seat held by  Rohrabacher  is key to Democratsâ hopes to increase their numbers in the U.S. House of Representatives in next yearâs elections. Neuroscientist Hans Keirstead  a stem cell researcher and entrepreneur from Laguna Beach  is one of seven Democrats aiming to beat him  according to the Federal Election Commission.

[Q]: Bitcoin's price has fully recovered from  its  recent slump after  JPMorgan CEO Jamie Dimon  called it a fraud and Chinese regulators cracked down on exchanges.
The cryptocurrency had a drawdown of up to 14% in the 10 days after September 12  when  Dimon  compared it to the tulip bubble of the 1600s and vowed to fire traders who used it.
By Thursday  bitcoin had all of the losses. It was up nearly 2% from the lows on the day  Dimon  spoke  at $4157.31 per coin at 10:28 a.m. ET.
The move illustrates bitcoin's wild volatility; it's gained 331% this year  unheard of for any major currency and most financial assets. It also shows why many Wall Street professionals like  Dimon  don't see it as a legitimate store of value but as a speculative instrument.

"It was at a ceremony the year after the attack  " Stone  recalls. "And afterwards we all huddled up and decided we needed to say something to  him . So we went back into the greenroom and said we have this book coming out and you should make the movie! So Mr Eastwood said to send  him  the book and gave us  his  address."

After school both  Stone and Skarlatos  opted for military careers - Stone in the US Air Force and Skarlatos in the Oregon Army National Guard. Did that military experience influence their split-second decision to try to take down El-Khazzani when he was intent on carnage?

Stone  who moments before had been dozing  charged down the train aisle as El-Khazzani levelled an assault rifle at  him .
But the weapon didn't fire  possibly because a bullet was faulty.  Stone  ended up with severe gashes to  his  neck and thumb after El-Khazzani lashed out with a box-cutter as they struggled hand-to-hand. Skarlatos and Sadler came to  Stone 's assistance.
"I wasn't really thinking about everyone else: I was just thinking about  myself  " says  Stone . "I just saw that something had to be done.
