MINNEAPOLIS (AP) -- Democratic officials and protesters on the streets are demanding that federal immigration officers leave Minnesota after a Border Patrol agent fatally shot a man in Minneapolis. Saturday's shooting drew hundreds of demonstrators into the frigid cold in a city already shaken by another killing weeks earlier.

The man killed by a US Border Patrol officer in Minneapolis was an ICU nurse, family says

MINNEAPOLIS (AP) -- Family members say the man who was killed by a federal officer in Minneapolis was an intensive care nurse at a U.S. Department of Veterans Affairs hospital who cared deeply about people and was upset by President Donald Trump's immigration crackdown in his city. Thirty-seven-year-old Alex Jeffrey Pretti was an avid outdoorsman who loved getting in adventures with his dog. He had participated in protests following the killing of Renee Good by a U.S. Immigration and Customs Law Enforcement officer earlier this month. Court records showed he had no criminal record. His family said he had never had any interactions with law enforcement beyond a could traffic tickets.

Trump threatens Canada with a 100% tariff over its China trade deal and escalates feud with Carney

WASHINGTON (AP) -- President Donald Trump is threatening to impose a 100% tariff on goods imported from Canada if America's northern neighbor goes ahead with its trade deal with China. Trump is intensifying a feud with Prime Minister Mark Carney, who's become a rising voice in the West's pushback to Trump's new world order. Trump said in a social media post Saturday that if Carney "thinks he is going to make Canada a "Drop Off Port" for China to send goods and products into the United States, he is sorely mistaken." It's unclear when Trump might impose the threatened tariff and the White House isn't offering additional details.

On the frigid Saturday morning, a Border Patrol agent shot and killed 37-year-old Alex Jeffrey Pretti after a scuffle. The shooting occurred amid daily protests in the Twin Cities. Numerous videos posted online offered different perspectives, and political leaders reached different conclusions from the footage.

Iran's Revolutionary Guard commander warns the US his force has its 'finger on the trigger'

DUBAI, United Arab Emirates (AP) -- The commander of Iran's Revolutionary Guard has warned that his forces are "more ready than ever" as U.S. warships move toward the Middle East. Tensions between Iran and the U.S. remain high following a crackdown on protests that began in December. Activists report over 40,000 arrests and a rising death toll. President Donald Trump has warned Iran against executing protesters and has moved warships "just in case." The situation has led some European airlines to suspend flights to the region. The U.N. has expressed concern over potential executions of detained protesters.

Trump housing finance chief OKs more mortgage spending and adds risk for government-backed lenders

WASHINGTON (AP) -- President Donald Trump's federal housing finance director, Bill Pulte, quietly granted government-backed lenders the authority to nearly double a $200 billion bond purchase that Trump ordered to try to lower mortgage rates. That's according to an email obtained by The Associated Press. The move could introduce a new level of risk for the companies. The purchasing rule changes would reverse nearly two decades of bipartisan consensus that limits should be imposed after the government bailed out Fannie Mae and Freddie Mac in the aftermath of the financial crisis of 2008-09. That crisis led to to them being placed into a government conservatorship.

Democrats Crockett, Talarico align on much in Texas Senate debate. Trump impeachment is different

Democrats Jasmine Crockett and James Talarici differed more on style than substance in their first debate for U.S. Senate in heavily Republican Texas. Crockett and Talarico generally echoed each other on economic issues, health care and taxes. But they distinguished themselves somewhat on the future of Immigration and Customs Enforcement and impeachment of President Donald Trump. The primary is March 3. They're running for the seat held by John Cornyn. The four-term Republican senator is facing two challengers in the GOP primary. Democrats are trying to regain a Senate majority, but Texas hasn't elected a Democrat to statewide office in 30-plus year.

Stranded by winter weather? Here's what airlines owe you

Bad weather can derail even the best-laid travel plans. When that happens, U.S. airlines must provide refunds for canceled flights. If winter weather is expected, airlines might also allow you to postpone your trip without fees. If your flight is canceled, airlines usually rebook for free, but availability can be limited during peak times. You are entitled to a full refund if you choose not to travel or find a different way to get to your destination, but airlines aren't required to cover lodging or meals for stranded passengers. Booking a backup flight if forecasts look bad is another option because some airlines offer full refunds as long as a passenger cancels within 24 hours of booking.

US envoys urge Netanyahu to move into Gaza ceasefire's second phase

CAIRO (AP) -- Top U.S. envoys have met with Israeli Prime Minister Benjamin Netanyahu, urging him to advance the ceasefire in Gaza. The meeting included U.S. President Donald Trump's envoy Steve Witkoff and Middle East adviser Jared Kushner. Details were not disclosed. The U.S. wants the Trump-brokered ceasefire deal to progress, but Netanyahu faces pressure to wait for Hamas to return the remains of a final hostage. The reopening of the Rafah border crossing between Gaza and Egypt is a key signal of the second phase. Meanwhile, an Israeli strike killed two Palestinian teens in Gaza. The ceasefire began on Oct. 10.
