Today's edition of quick hits:
* I can safely predict what Trump won't be tweeting about: "U.S. stocks fell sharply Friday, with the Dow Jones Industrial Average dropping by more than 650 points.... Friday capped an already tough stretch for the markets, with the Dow logging its worst week in two years."
* Sen. John McCain (R-Ariz.) appears to send a shot across Donald Trump's bow: "The latest attacks on the FBI and Department of Justice serve no American interests -- no party's, no president's, only Putin's."
* The retail apocalypse continues: "Several retailers have touted bonuses, employee raises and improved benefits as evidence that the new tax legislation is creating opportunities for the industry's workers. But even as these proclamations are being made, retailers are still closing stores and laying off staff."
* A story worth keeping an eye on: "Sen. Ron Wyden (D-Ore.) is seeking documents from the National Rifle Association (NRA) and the Trump Administration in order to determine whether 'Russian-backed shell companies' inappropriately sought to influence the 2016 election through the gun group."
* K.T. McFarland, "picked by President Donald Trump to be the U.S. ambassador to Singapore, withdrew from consideration for the job on Friday after her nomination became stalled in the U.S. Senate."
* San Francisco "is becoming a trailblazer in the new age of marijuana laws, saying it will dismiss all marijuana misdemeanor convictions dating back to 1975."
* Don't expect this to work: "The White House is considering presenting President Trump's Middle East peace plan even if the crisis with the Palestinian Authority continues and Palestinian President Abbas refuses to come to the negotiating table, senior U.S. officials tell me."
* I wish him well in this endeavor: "Preet Bharara's latest mission is to turn presidential norms into law."
