Investors looking to get a jump on White House announcements will be able to buy sneak peeks starting Saturday as a Trump family company starts selling special, fast access to the president's posts on social media. The new business targeting special computerized trading firms raises ethics questions about whether it constitutes insider trading and how far should a president be allowed to use his public office to help his private business. A prolific poster, Donald Trump has sent stocks soaring and plunging with his online musings and threats. The White House had no comment, and the company dismissed the ethics issue, saying Democratic critics just don't like free markets.
