WASHINGTON (AP) — A federal judge has ruled that former national security adviser John Bolton can move forward in publishing his tell-all book. The Trump administration had tried to block the release because of concerns that classified information could be exposed. The decision from U.S. District Judge Royce Lamberth is a victory for Bolton in a court case that involved core First Amendment and national security concerns. The ruling means a broader election-year readership and distribution for a memoir that paints an unflattering portrait of President Donald Trump's foreign policy decision-making during the turbulent year-and-a-half that Bolton spent in the White House. 686

WASHINGTON (AP) — Government scientists have classified 18 U.S. volcanoes as "very high threat" because of what's been happening inside them and how close they are to people.The U.S. Geological Survey has updated its volcano threat assessments for the first time since 2005. The danger list is topped by Hawaii's Kilauea , which has been erupting this year. The others in the top five are Mount St. Helens and Mount Rainier in Washington, Alaska's Redoubt Volcano and California's Mount Shasta ."This report may come as a surprise to many, but not to volcanologists," said Concord University volcano expert Janine Krippner. "The USA is one of the most active countries in the world when it comes to volcanic activity," she said, noting there have been 120 eruptions in U.S. volcanoes since 1980.RELATED: Hawaii's Kilauea could send 10-ton boulders half-mile into the airEleven of the 18 very high threat volcanoes are in Oregon, Washington and California.Government scientists use various factors to compute an overall threat score for each of the 161 young active volcanoes in the nation. The score is based on the type of volcano, how explosive it can be, how recently it has been active, how frequently it erupts, if there has been seismic activity, how many people live nearby, if evacuations have happened in the past and if eruptions disrupt air traffic.They are then sorted into five threat levels, ranging from very low to very high.RELATED: West Coast quake warning system now operational, with limitsDenison University volcanologist Erik Klemetti said the United States is "sorely deficient in monitoring" for many of the so-called Big 18."Many of the volcanoes in the Cascades of Oregon and Washington have few, if any, direct monitoring beyond one or two seismometers," Klemetti said in an email. "Once you move down into the high and moderate threat (volcanoes), it gets even dicier."The USGS said a dozen volcanoes have jumped in threat level since 2005. Twenty others dropped in threat level.RELATED: State's next big earthquake could be in SoCalThreat scores — and levels — change because of better information about the volcanoes, Klemetti said.Among those where the threat score — but not the threat level — is higher are Alaska's Redoubt, Mount Okmok, Akutan Island and Mount Spurr. Threat scores also rose for Oregon's Newberry Volcano and Wyoming's Yellowstone.None of the Big 18 changed in overall threat levels, even though 11 had overall threat scores dropping.Besides the top 5, the rest of the Big 18 are: Mount Hood, Three Sisters and Crater Lake in Oregon; Akutan Island, Makushin, Mount Spurr and Augustine in Alaska; Lassen and Long Valley in California; Mount Baker and Glacier Peak in Washington; and Mauna Loa in Hawaii. 2836

WASHINGTON (AP) — A speaker who had been scheduled to address the second night of the Republican National Convention has been pulled from the lineup after directing her Twitter followers to a series of anti-Semitic, conspiratorial messages.Trump campaign spokesperson Tim Murtaugh says, “We have removed the scheduled video from the convention lineup and it will no longer run this week.”Mary Ann Mendoza had been scheduled to deliver remarks Tuesday night to highlight the president’s fight against illegal immigration. Mendoza’s son was killed in 2014 in a head-on collision by a man who was under the influence and living in the U.S. illegally.She and and other parents whose children have been killed by people in the country illegally have labeled themselves “Angel Moms” and have made frequent appearances at the White House and Trump campaign events.Mendoza had apologized for the tweet, writing that she “retweeted a very long thread earlier without reading every post within the thread” and said it “does not reflect my feelings or personal thoughts whatsoever.”A Republican familiar with the plans who spoke on condition of anonymity cited controversy as the reason for pulling Mendoza. The Republican wasn't authorized to speak about the matter publicly. 1273
