[Q]: Facebookâs  first major investor Peter Thiel  has sold three-quarters of  his  remaining stake in the social network as part of a previously established trading plan  a regulatory filing showed.
 Thiel   who is a member of Facebookâs board  had already sold more than $1 billion worth of  its  stock before the filing made on Tuesday.
 It  said  he  had sold another 160 805 shares for about $29 million  leaving  his  holdings at 59 913 Class A shares in the company.
 Thiel  co-founded payment service PayPal and is known for funding the Hulk Hogan lawsuit that led to the shutdown of online news site Gawker. He became a Facebook investor in 2004 with an initial investment of $500 000 at a $5 million valuation.
When Zuckerberg took the company public in 2012   Thiel  sold 16.8 million shares at the IPO for about $640 million. Later the same year  he sold roughly 20 million of his remaining 26 million shares for $400 million after the expiry of a lockup.

[Q]: A woman runs past an Under Armour store in downtown Chicago on Oct. 16. (Christopher Dilts/Bloomberg)
Americans  it seems  are over Under Armour.
âThis is an abrupt about-turn for a company that  until recently  was on a mission to challenge the might of Nike â Neil Saunders  managing director of the analytical firm GlobalData Retail  said in an email. âUnder  Armour  has become just another brand in a sea of brands.â
The problems are multiple  he said. Although Under  Armour  racks up billions of dollars in sales each year  analysts say it has failed to drum up much loyalty among its customers. It has also been slow to resonate with women and has struggled to compete with larger rivals such as Nike and Adidas  which often offer lower-priced goods. Another factor: bankruptcy filings by key retail distributors such as Sports Authority and Sports Chalet.
âWe are incredibly disappointed with our 2017 performance â Kevin Plank  Under Armourâs founder and chief executive  said during the call with analysts. âWe have not performed to the level we had originally aspired to.â
Under Armour tried to keep up  he said  by discounting prices and offering more promotions than usual  which further cut into the companyâs profit margins. But  Plank added  those were just temporary efforts to shore up sales and not a long-term strategy for the company  which once could command higher prices than its competitors. (Menâs running shoes  for example  start at $74.99 at  Under Armour   $65 at Adidas and $60 at Nike  according to the companiesâ websites.)
âIn no way  shape or form do we anticipate changing the pricing model that makes Under Armour special and unique â Plank said. âWe invented the $25 T-shirt. Weâve pressed the bounds as to what consumers will pay for apparel. Thatâll continue. No one is looking for  Under Armour  to have the $25 hooded fleece. They want Under  Armour  at the $75 and $100 price points.â
But analysts say that might be a tough sell  particularly as customers grow accustomed to deep discounts. Saunders added that a âmarked slowdownâ in demand for athletic apparel is likely to further complicate Under  Armour âs turnaround efforts.
âWhile customer numbers have risen  loyalty to the brand is not deep-rooted in the same way that it is at Lululemon and Nike â he wrote. âWhat this means is that as demand moderated  Under  Armour  has been quick to drop off the radar of many consumers.â
The latest round of disappointing earnings comes on the heels of a tough year. The company posted its first-ever loss in April and in August announced it would lay off 2 percent of its workers. Thereâs also been changes to the leadership team. Still   shares of Under Armour stock  which are currently trading at about $13   have lost more than half  their  value this year.

[Q]: The reason  Trump  is able to tap into  his  campaign funds for legal expenses is because for the past decade  presidential candidates have abandoned public financing for their campaigns. Instead  they have built networks that collect millions of dollars from private donors  a move that comes with less restrictions on how the money is spent.
 Trump  also filed for reelection the day  he  took office in January  two years earlier than any previous president  ensuring a fund of millions in campaign cash would remain at  his  disposal.
According to  its  most recent filing to the Federal Election Commission  Donald J. Trump for President Inc had almost $12 million on hand by the end of June  an increase of over $4 million since January.
According to a July filing  the  Trump  campaign paid $50 000 to the law firm of Alan Futerfas  who is representing Donald Trump Jr. Futerfas did not respond for requests for comment.
A number of other current and former  Trump  staffers have also recently hired lawyers.
