question:
Fannie and Freddie buy mortgages and package them into securities with a guarantee against default.
 Fannie and Freddie have a legal right to return bad loans  especially if they later discover fraudulent statements on applications. Any money they recover offsets their losses.
 A bigger headache for lawmakers is figuring out what to do with Fannie and Freddie in the future.
 The Obama administration is working on a plan to restructure the mortgage market and make sure home loans are affordable. Officials don't plan to release details until next year. But Michael Barr  an assistant Treasury secretary  told the panel Wednesday that Fannie and Freddie "will not exist in the same form as they did in the past."
 Republicans have seized on the administration's management of Fannie and Freddie to illustrate Democrats' push for broadening the reach of the federal government. They say loans acquired by Fannie and Freddie since the September 2008 takeover have put taxpayers at risk.
 But Democrats and regulators say the loans acquired by Fannie and Freddie before their takeover represent the overwhelming majority of the companies' losses. New loans acquired since then have been performing well  they note.
 "There is no urgency " to reform the two companies  said Rep. Barney Frank  the committee's chairman. "The pattern of abuse they had engaged in has been changed...Fannie and Freddie are behaving differently and are causing far less problems."
answer:
Freddie Freddie


question:
The British cook attacked Nine Network's "A Current Affair" presenter Tracy Grimshaw at a Melbourne cooking expo on Saturday  the day after she interviewed him.
In front of thousands of onlookers  Ramsay suggested Grimshaw was a lesbian and needed "to see Simon Cowell's botox doctor."
He also showed a picture of a woman apparently naked on all fours with the face of a pig and said "that's Tracy Grimshaw." His publicist has since said the comments were a joke and not intended to cause offence.
Grimshaw also hit back at the "Hell's Kitchen" supremo  labelling him an "arrogant narcissist" on her current affairs show on Monday night.
She said there was nothing funny about Ramsay's insults  which had upset her friends and family  including her mother.
"Truly  I wonder how many people would laugh if they were effectively described as an old  ugly pig " she said  adding that she had agreed not to probe Ramsay over an extra-marital affair when he appeared on the show.
Grimshaw said she initially considered not responding to Ramsay's comments but decided she had to stand up for herself.
"We all know that bullies thrive when no one takes them on and I'm not going to sit meekly and let some arrogant narcissist bully me " she said.
"Obviously Gordon thinks that any woman who doesn't find him attractive must be gay " she added. "For the record  I don't. And I'm not."
answer:
Tracy Grimshaw


question:
A top engineering executive at Facebook announced Thursday night that  she 's leaving the company to work on shrinking a powerful medical technology.
 Mary Lou Jepsen   Facebook's executive director of engineering and the head of display technologies at Oculus â the social network's much-ballyhooed virtual reality product â made public  her  upcoming departure in August during a keynote talk in Silicon Valley.
"I have decided to leave Facebook and Oculus to work on curing diseases using some new imaging technologies I've been incubating for awhile  " Jepsen  said at the Anita Borg Institute's Women of Vision awards  an organization which describes  her  as "one of the world's foremost display innovators."
Additionally   Jepsen  said  she 's joined the board of directors of a "$20 billion automotive company that's listed on the New York Stock Exchange " adding that's  she 's "really interested to participate in helping steer the transformation of transportation."
A little more than a year ago   Jepsen  left Google's secretive research laboratory to work on Facebook's Oculus headset technologies. Prior to that   she  co-founded One Laptop Per Child  an organization that aims to make inexpensive computers and give them to children in developing nations.
 Jepsen  told the crowd Thursday night that  she  wants to shrink down magnetic resonance imaging (MRI) â machines used to image brain activity and normally fill an entire hospital room â into affordable  wearable consumer devices.
To that end   she  showed an image on stage of  her  vision  which is to essentially bring all of this tech into something that looks like a ski hat.
 Jepsen  teased a few possible applications of such a device  including to help treat cancer  cardiovascular disease  mental disorders  and neurodegenerative diseases. And in a bizarre twist   she  also said  her  concept might enable people to communicate with their thoughts.
It's uncertain exactly what the shrunk-down MRI technology might be called  how it might work  how far along in development it is  or if any of the applications  she  mentioned are even possible.
"I think that's the point of what we all should all be doing "  she  said. "Trying to make the impossible  possible."

Mary Lou Jepsen
