Republicans will keep control of the Senate, a result that was not unexpected but still never assured in this unpredictable political environment until voters had their say. The outcome represents a significant victory for the GOP and President Donald Trump.Despite a seemingly energized grassroots electorate, the Democratic Party has been viewed as a long shot to take back control of the Senate where Republicans currently hold a narrow majority of 51 seats to 49 seats for Democrats.PHOTOS: Election Day 2018 across the nationDemocrats face a daunting Senate map in the 2018 midterms and have been forced to defend 10 seats in states that President Donald Trump won in the 2016 presidential election, including North Dakota, Montana, West Virginia, Indiana and Missouri. 782

President-elect Joe Biden still has two more months before he is sworn in, and while many Republicans are finding it difficult to accept his win, Biden is meeting with key Democrats in hopes of having a deal in place for an economic stimulus plan. Biden has spoken with the top two Democrats in Congress — but not their Republican counterparts yet.Biden’s transition team announced Thursday that he spoke by phone with House Speaker Nancy Pelosi and Senate Democratic leader Chuck Schumer, thanking them for their congratulations and expressing “his commitment to uniting the country after a hard-fought campaign.”The three spoke about “intensifying” the country’s coronavirus response and coping with the economic fallout the pandemic has inflected. They also discussed the “urgent need” to use the lame duck congressional session to approve bills on slowing the spread of COVID-19, as well as economic relief for “working families and small businesses, support for state and local governments trying to keep front-line workers on the payroll,” expanded unemployment insurance and expanded access to affordable health care.Biden said Tuesday that he had not spoken to Senate Majority Leader Mitch McConnell, though the two have been friends for years.But there is still optimism this week among some on Capitol Hill a deal on economic stimulus can be approved during the lame duck session. "The need is too urgent. We need to do it now. Not wait. Families are going to be coming together, even though in smaller groups for Thanksgiving. They should have the assurance of another stimulus payment by Thanksgiving. It's doable," said Sen. Richard Blumenthal, D-Connecticut. 1680

President Donald Trump’s plans to kick off Independence Day with a showy display at Mount Rushmore are drawing sharp criticism from Native Americans who view the monument as a desecration of land violently stolen from them. Several groups led by Native American activists are planning protests for Trump’s July 3 visit, part of his “comeback” campaign for a nation reeling from sickness, unemployment and social unrest. But it comes amid a national reckoning over racism and a reconsideration of the symbolism of monuments around the globe. Many Native American activists say the Rushmore memorial is as reprehensible as the many Confederate monuments being toppled around the nation.The president's plans are also raising questions about fireworks safety. A fire expert says a fireworks display planned at the Mount Rushmore National Memorial is “ill advised” given the abnormally dry conditions and risk of summer wildfires. The July 3 event could attract 7,500 people. Bill Gabbert is the former fire management officer for Mount Rushmore and six other national parks in the region. Earlier this month, he said shooting fireworks over the extremely flammable ponderosa pine forest should not be done. The fireworks display at Mount Rushmore to celebrate Independence Day has not happened since 2009, when it was ended because of fire danger after a pine beetle infestation. Additionally, a 2016 U.S. Geological Survey report ties high levels of perchlorate contamination in the water at Mount Rushmore national memorial in South Dakota with past years of fireworks displays there. The pyrotechnics are set to resume this Independence Day holiday at the urging of President Donald Trump. 1698

President-elect Joe Biden met with his Transition Team's COVID-19 Advisory board for the first time on Monday morning, and delivered remarks following the meeting."I will spare no effort to turn this pandemic around when I'm sworn in on Jan. 20," Biden said.In his remarks, Biden congratulated Pfizer on the company's Monday announcement that early studies show its vaccine candidate is 90% effective in fighting the virus. However, Biden cautioned that even in best-case scenarios, the vaccine won't widely be available for several months. He promised that once vaccine candidates are approved, he will ensure that doses are distributed safely and efficiently.In addition, Biden called on manufactures to ramp up production of personal protective equipment and also said he planned to order more rapid test kits for use across the country.Finally, Biden spent several moments promoting the use of masks, calling them "the most potent weapon against the virus."It doesn't matter who you voted for...it doesn't matter your party or point of view," Biden said. "We could save tens of thousands of lives in the next few months if everyone just wears a mask."The address in Wilmington, Delaware came hours after Biden and Vice President-elect Kamala Harris announced the formation of a COVID-19 Advisory Board as part of their administration's White House Transition Team.The Biden-Harris Transition team said the board would consist of public health experts who will advise both Biden and Harris.“Dealing with the coronavirus pandemic is one of the most important battles our administration will face, and I will be informed by science and by experts,” Biden said in a press release “The advisory board will help shape my approach to managing the surge in reported infections; ensuring vaccines are safe, effective, and distributed efficiently, equitably, and free; and protecting at-risk populations.”The board consists of:CO-CHAIRSDr. David Kessler: Professor of Pediatrics and Epidemiology and Biostatistics at UCSF.
