Washington turmoil unnerves markets

Stocks fell sharply as investors worried that the latest turmoil in Washington could hinder President Donald Trump's pro-business agenda.

The steep drop Wednesday was the market's worst since September and ended an unusually long period of calm.

Banks, which soared in the months since the election, slumped.

The Standard & Poor's 500 dropped 43 points, or 1.8 percent, to 2,357. The Dow Jones industrial average lost 372 points, or 1.8 percent, to 20,606. The Nasdaq fell 158 points, or 2.6 percent, to 6,011, a day after its latest record high.

White House: Trump interviewing 4 FBI candidates

WASHINGTON The White House says President Donald Trump will be interviewing four potential candidates to lead the FBI, including former Connecticut Sen. Joe Lieberman.

White House press secretary Sean Spicer says Trump will be meeting later Wednesday with Lieberman, former Oklahoma Gov. Frank Keating, FBI acting director Andrew McCabe and Richard McFeely, a former top FBI official.

The meetings come more than a week after Trump fired FBI Director James Comey. The president has suggested he hopes to name Comey's successor before he departs Friday for his first overseas trip as president.

Talks on airplane laptop ban end with no ban, more talks

BRUSSELS Talks on a proposed U.S. ban on laptops and tablets in flights from Europe ended Wednesday with no ban and a promise of more talks and better intelligence sharing.

For days now, European Union officials have been hoping for details on the threat that prompted the proposed ban the same details that U.S. President Donald Trump discussed with Russian diplomats at the White House last week.

The airline industry came out against the proposal in a strongly worded letter that said it would cause a severe downturn in trans-Atlantic air travel and cost travelers more than a billion dollars in lost time.

On Wednesday, in a secure room in Brussels, officials from the U.S. Department of Homeland Security and the European Union swapped information about threats involving air travel. An official who followed the talks said the ban was "off the table" for now.

Gisele Bundchen: Tom Brady had a concussion last year

BOSTON Tom Brady played through a concussion last year on his way to a fifth Super Bowl title, according to his wife, supermodel Gisele Bundchen. The injury, which was not reported by the team, left her worried about how long he should continue to play football.

Asked if she wanted the New England Patriots quarterback to retire, Bundchen expressed concern "as a wife" in an interview on "CBS This Morning" that aired Wednesday.

"He had a concussion last year. He has concussions pretty much every ..." she said, before cutting herself off. "I mean, we don't talk about it. But he does have concussions. I don't really think it's a healthy thing for anybody to go through."

Brady sat out the first four games of the season as punishment for his role in the "Deflategate" scandal and missed practice late in the season for leg, thigh and ankle injuries. But he was not listed on the league-required injury reports for a concussion or head injury at any point during either the 2016 calendar year or the 2016 season.
