Mueller report, March Madness, Christchurch mosque reopens: 5 things to know this weekend

Content of Mueller's report submitted to attorney general remains unknown

The announcement followers of American politics have long been waiting for finally arrived Friday: the completion of the Mueller report. Special counsel Robert Mueller has finished his investigation into Russian interference in the 2016 election and his office delivered a report that signals the end of the inquiry that has loomed over Donald Trump's presidency. Attorney General William Barr acknowledged receiving the report, but he didn’t offer the probe’s conclusions and what the report says remains a mystery to most, including the White House. The Justice Department said a summary could become public as soon as Saturday. Early reactions have been measured, but most appear to agree on one thing: the full report should be made public. Democrats, Republicans, social media users and the USA TODAY Editorial Board all have called for the report’s release.

Flooding still possible in Midwest, days after 'bomb cyclone'

Last week's "bomb cyclone" storm that hit the Midwest may be in the past, but the aftermath created a "slow-moving natural disaster" with damages due to flooding totaling at least $3 billion. Water draining downstream is causing the Missouri River to rise across northeastern Kansas and Missouri, AccuWeather said. The river's water levels are forecast to challenge the crest record of 31.63 feet in Kansas by the weekend. The flooding stems from a storm that hammered more than a dozen states with heavy snow and rain. Since much of the region was already saturated or the ground frozen, the stormwater could not be absorbed. The result has been the current damage and the Mississippi River possibly remaining above flood stage "into the first part of the summer," AccuWeather said.

New Zealand mosque reopens for first time since deadly shootings

Worshippers returned to a New Zealand mosque Saturday when it reopened for the first time since a terrorist killed dozens of people there last week. Hundreds of people stopped at the Al Noor mosque in Christchurch, New Zealand, to lay flowers or pray after police removed a cordon and those running the mosque decided to reopen. The gunman killed a total of 50 people at two mosques in Christchurch on March 15, in the nation’s worst terrorist attack. Earlier this week, Prime Minister Jacinda Ardern declared a ban on military-style rifles, which includes assault rifles, high-capacity magazines and military-like semi-automatic rifles.
