Roger Stone, a longtime confidant of President Donald Trump, was sentenced to more than three years in prison Thursday for obstructing a congressional investigation in a case that has sparked fears about presidential interference in the justice system.

Soon after Judge Amy Berman Jackson pronounced sentence, Trump publicly decried Stone’s conviction as unfair and prominent Republican legislators were giving tacit support for a pardon. But Trump said he wasn’t ready to act just yet.

“I want the process to play out. I think that’s the best thing to do because I would love to see Roger exonerated,” he said. “I’m going to watch the process. I’m going to watch very closely. … At some point I’ll make a determination.”

The case was marked by the Justice Department’s extraordinary about-face on a sentencing recommendation and a very public dispute between Trump and Attorney General William Barr, who said the president was undermining the department’s historical independence and making “it impossible for me to do my job.”

The president responded by asserting that he was the “chief law enforcement officer of the federal government.”

Stone was convicted in November on all seven counts of an indictment that accused him of lying to Congress, tampering with a witness and obstructing the House investigation into whether the Trump campaign coordinated with Russia to tip the 2016 election.

He was the sixth Trump aide or adviser to be convicted on charges brought as part of special counsel Robert Mueller’s investigation into possible Russian interference in the 2016 election.

The Supreme Court is raising doubts about Alaska’s $500-a-year limit on contributions to political candidates. The justices are ordering a lower court to take a new look at the issue.

The court says in an unsigned opinion Monday that federal judges who had rejected a challenge to the contribution cap did not take account of a 2006 high court ruling invalidating low-dollar limits on political contributions in Vermont.

The Alaska challengers argue that the state is alone in imposing such low limits even on gubernatorial candidates “who must campaign across Alaska’s vast expanse and widely dispersed media markets.”

Justice Ruth Bader Ginsburg wrote in a short separate opinion that Alaska’s reliance on the energy industry may make the state unusually vulnerable to political corruption and justify low limits.

The father of two young girls found submerged in oil tanks after being missing for days told authorities his pregnant wife killed the children after learning he wanted a separation, and that he erupted in rage after witnessing the killings and strangled their mother inside the family's suburban Denver home, according to court documents.

Days after letting police inside his home so they could help find his missing family, Christopher Watts told investigators "he would tell the truth."

Watts first asked to speak with his father then admitted to killing his wife, Shanann. Watts told police in court papers released Monday that he killed her after witnessing her strangling one of the girls on a baby monitor. The other child had already been killed by the woman, he said.

Watts, 33, faces three first-degree murder charges, two counts of murdering a child under 12, one count of unlawful termination of a pregnancy and three counts of tampering with a deceased human body. He is scheduled to appear in court on Tuesday and is being held without bail.

District Attorney Michael Rourke declined to answer questions about the case Monday but said his office has three prosecutors working on it. Rourke also said it was too early to discuss whether he will seek the death penalty.

Police first visited the family's house on Aug. 13, after a friend asked officers to check on Shanann Watts. She had missed a doctor's appointment and wasn't answering calls or text messages hours after returning home after a business trip, the friend reported.

Zimbabwe's president says people are free to approach the courts if they have issues with the results of Monday's election, which he carried with just over 50 percent of the vote.

President Emmerson Mnangagwa spoke to journalists shortly after opposition leader Nelson Chamisa called the election results manipulated and said they would be challenged in court. Chamisa received 44 percent of the vote but says his supporters' own count gave him 56 percent.

Mnangagwa is praising the vote as free and fair despite the opposition concerns and those of international election observers who noted the "extreme bias" of state media and the "excessive" use of force when the military cracked down on opposition protesters in the capital on Wednesday.

The president also is looking forward to his inauguration, saying that under the constitution it should happen nine days after election results are declared.

Zimbabwe's president is praising "a free, fair and credible election, as we have always promised" and "unprecedented flowering of freedom and democracy in our beloved homeland" even as the opposition loudly rejects the results.

President Emmerson Mnangagwa spoke shortly after opposition leader Nelson Chamisa said Monday's peaceful election had been manipulated and said the results would be challenged in court.

Mnangagwa, a former enforcer of longtime leader Robert Mugabe, has tried to recast himself as a voice of change. He is calling the deadly violence against opposition supporters in the capital on Wednesday "unfortunate" and says Chamisa has a crucial role to play in Zimbabwe's future.

German officials say there's been a sharp drop in sales of new diesel cars, following a court decision that allows cities to ban the use of heavily polluting vehicles.

Figures released Wednesday by the Federal Motor Transport Authority show new registrations of diesel-powered cars dropped by 25.4 percent in March to under 109,000, compared with about 146,000 during the same month a year earlier.

Germany's top administrative court ruled Feb. 27 that cities can ban diesel cars and trucks to combat air pollution. The decision is a further blow to diesel fuel technology after the revelations that German automaker Volkswagen cheated on U.S. emissions tests.

The value of diesel vehicles in Germany already had fallen significantly, and their market share has fallen since the VW scandal broke in 2015.

North Dakota's attorney general is applauding a U.S. Supreme Court ruling that recognizes federal district courts as the forum to hear legal challenges to an Obama administration rule aimed at protecting small streams and wetlands from development and pollution.

Attorney General Wayne Stenehjem led a coalition of 12 states that obtained the first preliminary injunction against the "Waters of the U.S. Rule" in 2015 in North Dakota, arguing it would greatly and unlawfully expand the federal government's authority over states' land and water and the ability to control pollution.

The rule has never taken effect because of lawsuits and is now under review by President Donald Trump's administration.

Stenehjem says he'll ask the federal district court to resume North Dakota's case as soon as possible now that the jurisdiction issue has been resolved.
