MINNEAPOLIS (WCCO) — From a major outage creating problems for Delta Air Lines to new e-cig regulations in effect, here are the four things to know for Monday, Aug. 8.

Delta Power Outage Causes Major Backups

Delta flights around the world are grounded after major issues with the airline’s computer system. That’s caused backups at airports, including MSP International.

A power outage in Atlanta has caused major issues with its computer system.

Until it’s fixed, all flights around the world are grounded.

Delta does not know how much longer this will last.

Trump To Give Economy Speech In Michigan

Donald Trump is set to deliver a major economic speech in Michigan Friday.

Over the weekend, the Republican nominee repeatedly questioned Hillary Clinton’s mental health after she said she “short-circuited” her response to questions about the FBI’s investigation into her email scandal.

Clinton, who leads Trump in several national polls, will offer up her own vision for the economy in Detroit Thursday.

E-Cig Regulations Now In Effect

New federal regulations of e-cigarettes go into effect. The FDA will now require greater scrutiny of e-cigs and make it more difficult for minors to vape.

Shops will also not be able to give out free samples to customers.

Before the new regulations, there was no federal law prohibiting retailers from selling e-cigs, hookah tobacco or cigars to minors.

A-Rod To Retire

Yankees slugger Alex Rodriguez is calling it quits. He’ll hang up his cleats after Friday’s game against Tampa Bay and become a special assistant to the Yankees.

The 41-year-old played for 22 years and is a three-time American League MVP and 14 time all-star.

He sat out all of 2014 after being suspended for performance-enhancing drugs.
