The school year has come to an abrupt end for students across Kansas.

Gov. Laura Kelly announced that she has ordered classes K-12 to be closed for the remainder of the 2019-2020 school year, citing fears about the spread of the coronavirus disease COVID-19 and the "unprecedented emergency" it presents.

"This was not an easy decision to make," Kelly said in a statement issued Tuesday.

"It came after close consultation with the education professionals who represent local school boards, school administrators and local teachers," she explained. "These unprecedented circumstances threaten the safety of our students and the professionals who work with them every day and we must respond accordingly."

Kelly's executive order makes Kansas the first state to shut down its public schools for the remainder of the school year — an extraordinary step that other states so far have been reluctant to take, despite a raft of temporary class closures across the U.S.

All told, three-quarters of all K-12 students in the U.S. — including those in Michigan, Massachusetts and Kentucky — have seen their schools shuttered for a span of several weeks, though officials there hope students will still be able to return before summer sets in. It's worth noting that the school year in Kansas begins and ends several weeks earlier than it does in most other states.

Governors in Ohio and California, however, suggested that it might be just a matter of time before their states follow Kansas' lead. California Gov. Gavin Newsom has stopped short of making it official, but at a news conference Tuesday, he told reporters that "it's unlikely that many of these schools — few if any — will open before the summer break."

"This is a very sobering thing to say," Newsom added. "I don't want to mislead you."

Trump announces temporary closure of U.S.-Canada border

President Trump has announced that the border between the U.S. and Canada will be closed in an attempt to stem the spread of the novel coronavirus. The president announced the closure in a tweet posted Wednesday.

"We will be, by mutual consent, temporarily closing our Northern Border with Canada to non-essential traffic," Trump said, adding that "trade will not be affected."

Trump gave no further details on the border closure. The announcement came just hours after the U.S. death toll from COVID-19 crossed a sobering threshold, topping 100 deaths.

Canadian Prime Minister Justin Trudeau has not yet independently confirmed Trump's statement; he is expected to deliver a statement from self-isolation later Wednesday. Canada has seen a much smaller — though also increasing — number of confirmed cases than the U.S.

The move is just the latest of a series of border shutdowns announced recently across the world, as countries seek to tamp down on travel in an effort to slow the spread of the global pandemic.

Trump administration asks for tens of billions in emergency funds

The request to Congress, which asks for an additional $45.8 billion, is intended to support the Centers for Disease Control and Prevention, states' public health response and research resources at the National Institutes of Health. It is in addition to a House-approved relief package that's expected to go before the Senate on Wednesday.

"The aim of this request is to maintain that capacity and ensure that resource needs created by the pandemic response are met," Russ Vought, acting director of the Office of Management and Budget, said in a letter to Vice President Pence

Vought noted that his office is "currently in active dialogue" with lawmakers about the additional proposal, which is separate from a massive stimulus package that's expected to include payments to individuals, families and businesses affected by the outbreak.

"It is not intended as a broad-based solution to the major economic dislocation wrought by the virus, nor is it the primary means by which the Federal Government plans to address the hardships of families, individuals, and communities who have been touched by the disease."

Puerto Rico asks the FAA to halt flights to the island

Puerto Rico Gov. Wanda Vázquez revealed that she has asked the Federal Aviation Administration to suspend domestic and international flights to the U.S. territory, as local authorities seek to contain the virus.

Vázquez said the requested ban would exempt emergency services. Puerto Rico has already imposed some of the strictest restrictions in the U.S., including a curfew and the two-week closure of most businesses across the island.

"Until a few days ago, we had no cases of COVID-19 coronavirus, and now, due to the arrival of tourists, both by boat and by plane, we have five positive cases," she said in a statement Wednesday.

"We do not want more cases in Puerto Rico, and the only way to prevent more people infected with this virus from arriving is by taking greater controls regarding the arrival of travelers. We need assistance from the federal government to allow us to control air travel."
