[Q]: Tensions between Republicans and Democrats over the investigation of Russian involvement in the 2016 presidential election intensified Sunday  with President Donald Trump demanding to know why his campaign is under federal scrutiny while his former opponent Hillary Clinton is not.
Democratic lawmakers mostly stayed out of the Sunday fray after a week in which  Clinton 's 2016 campaign came under fresh scrutiny. The campaign funded political opposition research into Trump that helped create a highly publicized "dossier" on the Republican candidate and fueled some allegations now under scrutiny by Mueller.
It's unclear how much the  Clinton  campaign and Democratic National Committee paid for the opposition research by Fusion GPS  a Washington  D.C.  firm that conducts investigations for private clients. The  Clinton  campaign paid $5.6 million in legal fees to a law firm from June 2015 to December 2016  according to campaign finance records  and the DNC paid the firm $3.6 million in "legal and compliance consulting'' since November 2015. It's impossible to tell from the filings how much of that work was for other legal matters and how much of it related to Fusion GPS.
Trump tweeted Sunday morning that the dossier  which he called " Clinton  made Fake Dossier " could have cost as much as $12 million  although he did not explain how he reached that number.
In April 2016  an attorney representing  Clinton 's presidential campaign and the DNC hired Fusion GPS  which then hired Steele. Brian Fallon  a former spokesman for the  Clinton  campaign  said he learned about Steele and the dossier after the election. People familiar with the matter told The Washington Post that the  Clinton  campaign and the DNC did not direct Steele's activities.

[Q]: "People have a very exaggerated idea of the benefits " said Dr. Rita Redberg   a professor of medicine at University of California  San Francisco and the editor-in-chief of the journal JAMA Internal Medicine.
This is different from secondary prevention: the use of statins to prevent heart attacks and strokes in people who have already had one.  Redberg  said the evidence for this is much stronger.
Out of 100 people taking primary preventive statins for five years  "the best estimates are that one or two people will avoid a heart attack  and none will live longer  by taking statins "  Redberg  said.
But  Redberg  said that there are plenty of experts without conflicts of interest  which is important to keep in mind when considering top-selling drugs like statins.
"It's billions of dollars here "  she  said. "You can't ignore that."

[Q]: In late March   Timothy Nguyen   a 25-year-old coach at Quicksilver  a USA Swimming-affiliated club in San Jose  quit after an underage swimmer told the clubâs head coach that  Nguyen  had sent her suggestive messages through social media. The head coach informed USA Swimming officials  but no one told law enforcement.
Two months later  on May 30  Elizabeth Hoendervoogt  a USA Swimming official and abuse prevention specialist  called San Jose police to report  Nguyen  and send over messages the coach had exchanged with three swimmers  all aged 14 to 16.
In one exchange  police allege   Nguyen  asked a girl if sheâd been sexually active yet  discussed the specifics of several sex acts and then suggested they could be âfriends with benefits.â In another  police say   Nguyen  asked a girl for nude photos. One girl told police she had improved as a swimmer under Nguyen  and she had been concerned  he  would stop coaching her if she didnât respond.
In late June  police arrested  Nguyen . Then they learned Quicksilverâs head coach and USA Swimming officials had known about some of Nguyenâs behavior in March. In California  coaches are mandatory reporters and must inform authorities within 36 hours of learning of suspected sex crimes involving children.
USA Swimming spokesman Matthew Farrell said it took two months for the Olympic sports organization to report  Nguyen  to police because it took time to collect the text messages. When asked whether USA Swimming or the club should have handled the report differently  Farrell replied: âIâm not aware of any substantive changes that USA Swimming or the club would make.â
