Collapse: A pedestrian bridge described as a wonder of engineering built for Florida International University in Miami collapsed yesterday on eight cars, killing at least six people. The 90-ton bridge, which had been built on the ground and moved into place only on Saturday, had not even opened for people to walk across it. The bridge was built for students living in an adjacent neighborhood to safely cross a busy road.

Workers were still tightening cables when the bridge collapsed.

Cars passing under had stopped for a red light. Other motorists jumped to rescue those who were trapped, but quickly realized they could not reach people in cars that had been pancaked. Responders used rescue dogs, listening devices, and fiber optic cameras to search for survivors. At least nine people were pulled from the rubble.

House Cleaning: President Trump has decided to fire his national security adviser, Gen. HR McMaster, The Washington Post reports.  It’s been reported for months that the two never got along.

CBS News also reports that Chief of Staff John Kelly may be gone as soon as today.

The Post reports of recent firings, including that of Secy. of State Rex Tillerson, “The turbulence is part of a broader potential shake-up under consideration by Trump that is likely to include senior officials at the White House, where staffers are gripped by fear and un­certainty as they await the next move from an impulsive president who enjoys stoking conflict.”

Candidates for firing also include Housing Secretary Dr. Ben Carson, who evidently lied about trying to buy $31,000 worth of furniture for his executive dining room; Veterans Affairs Secretary David Shulkin, who used taxpayer money for his wife to go to Europe; EPA Administrator Scott Pruitt, who has a fondness for expensive air travel; Interior Secretary Ryan Zinke, who also prefers to go big while going home; and finally, Atty. General Jeff Sessions, who has Trump in a permanent twist for recusing himself from the Russia investigation.

Reports now say Trump’s personal assistant, John McEntee, was fired Monday because he has a serious gambling habit — not good for someone with a security clearance.

Follow the Money: Special Counsel Robert Mueller has subpoenaed business records of the Trump organization, bringing the Russia investigation closer to the President himself, The NY Times reports. The investigation appears to be examining the role of foreign money in Trump’s business and political activities, the paper reports. The Times  says the subpoena demands documents related to Russia and other matters.

It’s the first time, at least to public knowledge, that Robert Mueller has sought documents from the Trump business. The subpoena, and other activities by the Social Counsel, indicate that the investigation is widening and likely to continue longer than the Trump administration has predicted.

The Russia House: President Trump has been mysteriously non-critical of Russia’s election hacking and cyber-attacks around the world, but yesterday his administration finally slapped sanctions on five Russian organizations and 19 people cited for spreading disinformation and propaganda to disrupt the 2016 election. The sanctions pretty much overlap the indictments brought by Special Counsel Robert Mueller, with the addition of a few people.

Possibly more ominously, the administration cited the Russian government for hacking into American power plants and computer networks that control them at about the time of the election. The NY Times reports that, “Those attacks suggest Russian state-sponsored hackers have been actively mapping out Western industrial, power and nuclear facilities for eventual sabotage, experts say.”

Trump continues to say nothing about Russia’s election influencing. He did finally mention Russia in comments about the nerve agent attack in Britain. “It certainly looks like the Russians were behind it,” he told reporters in the Oval Office. “Something that should never ever happen. We’re taking it very seriously, as I think are many others.”

Like Father: Vanessa Trump, wife of Donald Trump Jr., filed for divorce yesterday in New York City. The Trumps, both 40, have been married 12 years and have five children. The divorce filing suggests that Vanessa has no intention of fighting about money or child custody. The Trumps have a tradition of pre-nuptial agreements and Junior is travelling all the time anyway.

The news has been met with glee on the internet, although some defenders say it’s sad and the couple should be left alone. We agree. The wife and kids are off limits, but the elephant-hunting Don Jr. is fair game.

Your Congress in Action: In response to the death of a puppy on United Airlines, Florida Republican Sen. John Kennedy bravely tweeted yesterday that he has proposed a new law directing the FAA “to create regulations to prohibit the storing of a live animal in any overhead compartment and establish civil fines for violations.” Congress meantime, has done nothing about gun control or mass shootings. One of Kennedy’s critics quickly responded, “ITS TOO SOON TO TALK ABOUT OVERHEAD BIN PET CONTROL.”
