Donald Trump

If it's been a few years since you shopped for a lightbulb, you might find yourself confused. Those controversial curly-cue ones that were cutting edge not that long ago? Gone. (Or harder to find.) Thanks to a 2007 law signed by President George W. Bush, shelves these days are largely stocked with LED bulbs that look more like the traditional pear-shaped incandescent version but use just one-fifth the energy.

There were two headline "principal conclusions" out of Attorney General William Barr's publicly released letter to Congress about the now-concluded Russia probe conducted by special counsel Robert Mueller:

1. It "did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. presidential election."

Special counsel Robert Mueller's work is done, but the Russia imbroglio likely has a few more encores before the curtain closes.

Attorney General William Barr notified Congress on Sunday of a huge milestone in the saga: Mueller has submitted a report that did not find that President Trump's campaign conspired with the Russians who interfered in the 2016 election.

Leaders of the Justice Department have sent a summary of Robert Mueller's main findings to key members of Congress. The special counsel's office completed its investigation into Russian interference in the 2016 presidential election on Friday.

President Trump said Friday he will nominate conservative TV commentator and former Trump campaign adviser Stephen Moore to one of two vacant seats on the Federal Reserve Board.

Moore, 59, has joined the president in criticizing the central bank, led by Chairman Jerome Powell, for raising interest rates.

"I have known Steve for a long time — and have no doubt he will be an outstanding choice!" Trump said in a tweet.

With just over a week to go until the deadline for the United Kingdom to leave the European Union, the son of President Trump says that everything would be on track had British Prime Minister Theresa May taken his father's advice on Brexit.

High-ranking Democrats on Capitol Hill are calling for a counterintelligence investigation into a woman who has peddled access to President Trump and who founded the massage parlor where New England Patriots owner Robert Kraft is accused of soliciting sex.

President Trump used his veto pen for the first time Friday, after Congress tried to reverse his national emergency declaration and rein in spending on a wall along the U.S.-Mexico border.

Congressional critics do not appear to have the votes to override Trump's veto. So, as a practical matter, the administration can continue to spend billions of dollars more on border barriers than lawmakers authorized, unless and until the courts intervene.

Nowhere else in the House of Representatives is the tension between legislation and investigation more present than on the House Transportation and Infrastructure Committee, where a bipartisan infrastructure deal could be in the making — even as the Democrats on the committee launch a reinvigorated investigation into the D.C. Trump International Hotel.
