The Supreme Court appeared ready Tuesday to uphold voting restrictions in Arizona in a key case that could make it harder to challenge a raft of other voting measures Republicans have proposed following last year’s elections.

All six conservative justices, appointed by Republican presidents, suggested they would throw out an appellate ruling that struck down the restrictions as racially discriminatory under the landmark Voting Rights Act. The three liberal members of the courts, appointed by Democrats, were more sympathetic to the challengers.

Less clear is what standard the court might set for how to prove discrimination under the law, first enacted in 1965.  The outcome could make it harder, if not impossible, to use the Voting Rights Act to sue over measures making their way through dozens of Republican-controlled state legislatures that would make it more difficult to vote.

Civil rights group and Democrats, argue that the proposed restrictions would disproportionately affect minority voters, important Democratic constituencies.

Democrats in Congress, meanwhile, have proposed national legislation that would remove obstacles to voting erected in the name of election security.

A man and two companies in Alaska have been sentenced to three years probation and a $35,000 fine for violating the Clean Air Act involving asbestos work at a shopping center more than five years ago, a judge said.

The work was performed at the Northern Lights Center in Anchorage, the former location of an REI store. Reports of potential asbestos exposure at the time closed the store for a day back in 2015, authorities said.

U.S. District Court Judge Joshua Kindred sentenced Tae Ryung Yoon, 64, on Friday to probation, fined him $35,000 and said he owes $30,000 in restitution for medical monitoring of the four workers who claimed they were exposed to asbestos, the Anchorage Daily News reported.

The owners of Yoo Jin Management Company Ltd. and Mush Inn Corp. were also sentenced after agreeing to plead guilty to a charge of violating the Clean Air Act’s Asbestos Work Practice Standards. Both companies are owned by Chun Yoo, who is in his 80s and has “serious medical conditions,” and his wife, attorney Kevin Fitzgerald said. The couple still owns the center.

The case centers on workers who said they were exposed to asbestos during improperly conducted renovations involving an old boiler room. The work was stopped when two of the workers raised concerns.

High levels of asbestos exposure can cause lung disease or cancer.

Prosecutors said in a statement that the building owners and manager relied on a contractor who was not a certified asbestos abatement contractor and “failed to inform the contractor of the possibility of asbestos in the old boiler room.”

Fitzgerald argued that an assessment indicated no evidence of asbestos when his clients bought the center in 2006. Yoon was the building’s property manager at the time.

Documents show the boilers were replaced by another company in 2012 and the old ones were removed in 2014 to make more room. Some of the workers took photos of what they thought was asbestos and emailed them to the property management company that employed Yoon.

Labor union members plan to hand out personal protective equipment outside the sports complex where members of the New Hampshire House will be meeting this week.

The 400-member House is meeting Wednesday and Thursday in Bedford, where they will sit 10 to 12 feet apart to prevent spread of COVID-19. Democrats with serious medical conditions went to court seeking remote access to the sessions, but a federal judge declined Monday to order  Republican Speaker Sherm Packard to accommodate them.

While the House will provide members with masks and hand sanitizer, members of the International Union of Painters and Allied Trades and the AFL-CIO of New Hampshire also will be at the facility’s entrances with similar supplies, including mask and gloves.

One New Hampshire school is planning to hold remote learning for two weeks following the winter vacation, despite Gov. Chris Sununu’s executive order requiring schools to offer in-person instruction to all students for at least two days, starting March 8.

The decision regarding Profile School in Bethlehem, which would be in effect as of March 1, is not expected to conflict with the order, Kim Koprowski, chairperson of the school board, said Monday, the Caledonian-Record reported. The school serves students in grades 7 through 12.

“My understanding of it is there were a handful of schools in the state that are totally remote and he is trying to push those to go to two days a week,” she said. “Since we have been doing that all year, we’ve been face to face, with the exception of a remote period. You could call us hybrid. We should be good.”

A message seeking comment was left Tuesday with the state Education Department. The executive order allows schools to return to remote learning for 48 hours if necessary due to COVID-19 infections. After that, state approval would be required.

Koprowski said that although COVID-19 numbers are trending down, “they are still not at the level they were last fall before Thanksgiving and Christmas.”
