White House lawyer Ty Cobb is leaving his position, the White House said Wednesday."For several weeks Ty Cobb has been discussing his retirement and last week he let chief of staff (John) Kelly know he would retire at the end of this month," White House press secretary Sarah Sanders said in a statement.The New York Times first reported the news."It has been an honor to serve the country in this capacity at the White House," Cobb told the Times. "I wish everybody well moving forward."The Times, citing two people briefed on the matter, said attorney Emmet Flood would replace Cobb as the President continues to grapple with the special counsel investigation led by former FBI Director Robert Mueller. Flood represented then-President Bill Clinton during his impeachment process in the late 1990s.Cobb, a former federal prosecutor, joined Trump's legal team in July 2017. 882

While the Centers for Disease Control and Prevention is urging Americans not to travel this holiday season, it's clear that many will choose to do so anyway.Between Nov. 25 and Nov. 29 — the height of the Thanksgiving travel surge —the Transportation Security Agency (TSA) said it screened about 4.5 million travelers. While that represented 39% less travelers than last year, it represented the most travelers the agency had screened since the start of the pandemic.With another surge in travel expected for Christmas and New Year's, the TSA has offered some helpful tips when it comes to packing luggage for the holiday season.Packing giftsDo not pre-wrap gifts: Gifts need to be screened like any other piece of luggage, meaning gifts need to be unwrapped if they need to be inspected. The TSA suggests wrapping once you reach your destination, or wrapping in a gift bag.Be sure to pack gifts that contain large amounts liquid, like perfumes, gel candles or snow globes, in a checked bag. TSA allows containers with 3.4 ounces of liquid or less for carry-ons.Snowboards, snowshoes and ice skates can be carried on, but be sure to check with airlines about a plane's overhead bin space. Skis and ski poles will need to be checked.Packing foodHomemade baked goods and other treats can be carried on, but any sort of jams, jellies or syrups are liquids and should be checked if they're in a container larger than 3.4 ounces. A rule of thumb? "If you can spill it, spray it, spread it, pump it or pour it, then it should be packed in a checked bag if the container is larger than 3.4 ounces."Higher-proof alcoholic beverages (between 24% and 70% alcohol by volume) are limited in check bags to five liters a passenger. Any beverage with less than 24% alcohol by volume has no size limit in a checked bag.Mini bottles of alcohol can be carried on, as long as they are less than 3.4 ounces and fit "comfortably" in a single quart-sized bag.Packing electronics Electronics to be given as a gift can be carried on, but remember to place electronics larger than a laptop in their own bin with nothing above or below it.TSA allows drones past checkpoints, but double-check with airlines on their policies about transporting drones.Remember, loose lithium batteries are prohibited in checked bags.

With hurricane season in full swing, there's a lot of talk from meteorologists about hurricane "categories." What do they mean, and what do they tell us about a storm?It turns out, a hurricane's category is only based on one thing: wind speed.According to the National Hurricane Center's website, the agency relies on the Saffir-Simpson Hurricane Wind Scale to determine a storm's strength. The scale categorizes a hurricane on a 1-5 scale, based on the storm's maximum sustained winds — the one-minute average of the wind speed taken from inside the storm.When storms over the Atlantic begin to organized into a rotating system around a central "eye," and sustained wind speeds in the storm reach 39 mph, it's classified as a tropical storm. Once wind speeds in the system reach 74 mph, it becomes a hurricane.From there, the NHC uses the Saffir-Simpson Scale to determine how much destruction a hurricane is expected to inflict on an area. While any hurricane is expected to cause damage to homes and topple some trees in its path, higher wind speeds can lead to trees blocking roads and downing power lines, isolating communities without power or access to water for weeks — or even months.STRENGTHMAX SUSTAINED WIND SPEEDDESTRUCTION CATEGORY 1Between 74 mph and 95 mphWell-constructed houses could have damage to roof, shingles, vinyl siding and gutters. Large branches of trees will snap and shallowly-rooted trees may be toppled. Extensive damage to power lines and poles likely will result in power outages that could last a few to several days. CATEGORY 2Between 96 mph and 110 mphHouses could sustain major roof and siding damage. Many shallowly rooted trees will be snapped or uprooted and block roads. Near-total power loss is expected with outages that could last from several days to weeks. CATEGORY 3 (major)Between 111 mph and 129 mphHouses may incur major damage or removal of roof decking and gable ends. Many trees — regardless of root depth — will be snapped or uprooted, blocking roads. Electricity and water will be unavailable for several days to weeks after the storm passes.CATEGORY 4 (major)Between 130 mph and 156 mphHouses can sustain severe damage with loss of most of the roof structure and possibly some exterior walls. Most trees will be snapped or uprooted and power poles will topple. Fallen trees and power poles will isolate residential areas. Power outages will last weeks to possibly months. Most of the area will be uninhabitable for weeks or months.CATEGORY 5 (major)Above 157 mphA high percentage of framed houses will be destroyed, with total roof failure and wall collapse. Fallen trees and power poles will isolate residential areas. Power outages will last for weeks to possibly months. Most of the area will be uninhabitable for weeks or months.Any hurricane that reaches Category 3, with sustained winds above 111 mph, is considered a "major" hurricane. According to the NHC, that's because "of their potential for significant loss of life and damage." But that doesn't mean Category 1 and 2 hurricanes can't be deadly.The NHC itself says that Category 1 and 2 hurricanes are "still dangerous" and "require preventative measures."While Hurricane Sandy peaked at Category 3 intensity when it made landfall in Cuba in 2012, it had collapsed into a post-tropical cyclone by the time it reached New Jersey on Oct. 29. Even though the storm only had Category 1 strength winds, it still resulted in the deaths of 131 people in America, according to media reports, and an estimated billion in damages — the second-costliest hurricane in U.S. history up to that point.The Saffir-Simpson Scale also doesn't take into account storm surge in coastal areas and flash flooding caused by the surge and heavy rain. Flooding can cause significant property damage and make main roads — including expressways — inaccessible. 3864

While fans are not allowed to attend any MLB games in the shortened 2020 season, the Oakland Athletics came up with a brilliant way to "bring in" fans.The team unveiled its "Coliseum Cutouts" program, where A's fans will get a chance to display the cardboard cutout of themselves during games.The team's staff will try to fill the stands with the cutouts. Prices range from to 9 for each cutout. If a cutout in the program's foul ball zone gets hit with a foul ball, the A's will send the ball to that fan.Proceeds from this program will benefit the team's charity partners.With every purchase of a cutout, the fan will also receive two complimentary tickets to the A's first exhibition game at the Coliseum during the 2021 season. WFTS' KJ Hiramoto first reported this story. 794

White House chief of staff John Kelly has been locked in an internal struggle with President Donald Trump's son-in-law and senior adviser Jared Kushner over his access to highly classified information for weeks now, a confrontation that has escalated amid a recent policy overhaul and the resignation of a staff secretary who was accused of spousal abuse.The dispute has deepened a growing rift between Kelly and Kushner, who initially welcomed the new system of rigor instituted by the chief of staff but has since grown frustrated by what he views as attempts to limit his access to the President.Kelly distributed a five-page memo Friday announcing that the White House will no longer allow some employees with interim security clearances to access to top secret information if their background investigation has been pending since before last June -- a category Kushner falls into.  899
