There were some acerbic and personal comments from the justices of the Supreme Court on Wednesday, as they heard an age discrimination case that could affect more than a million federal workers over the age of 40.

The federal law says that "all personnel decisions" made in the federal workforce "shall be made free from age discrimination."

The Equal Employment Opportunity Commission has long interpreted that to mean that if a federal worker can show that age was a factor in denying her a job or promotion, the worker is entitled to back pay or other remedies.

The U.S. Supreme Court on Tuesday weighed whether to make life more difficult for prosecutors in public corruption cases.

The modern-day court has made it increasingly difficult to prosecute public officials who abuse their power but don't personally enrich themselves. The court has thrown out multiple public corruption convictions in recent years, all but eviscerating broad statutes aimed at ensuring the honest services of public employees.

"Bridgegate" was the political scandal that marked the beginning of the end of New Jersey Gov. Chris Christie's presidential hopes. The scandal's legal consequences could prove more consequential if, as prosecutors fear, the criminal convictions in the case are thrown out by the Supreme Court.

On Tuesday, the justices will revisit the case that made headlines in 2013 on the first day of school when, unbeknownst to the public, officials close to Christie ordered the shutdown of two of three access lanes from Fort Lee onto the George Washington Bridge.

When the Senate impeachment trial of President Trump opens, the man in the center chair will be Chief Justice John Roberts. His role is spelled out in the Constitution.

Twenty-one years ago Thursday, as the House approved articles of impeachment against President Bill Clinton, Senate Majority Leader Trent Lott was sitting in his study in Pascagoula, Miss., "looking out on a beautiful live oak tree." With a sigh, the Republican leader picked up the phone to call Senate Minority Leader Tom Daschle, his Democratic counterpart.

"Whether we like it or not, this is sitting in our lap," he told Daschle, "and we've got to figure out how to deal with it."

Lott was a skilled vote-counter.

The U.S. Supreme Court examined Obamacare for the fifth time on Tuesday, only this time the justices cast their skeptical gaze on Republican efforts to hobble the law.

Enacted by a Democrat-controlled Congress in 2010, the Affordable Care Act promised to partially reimburse insurers if they lost money by covering people with preexisting conditions. The law said that the government "shall" make these payments. But in 2015, Republicans, by then in control of both houses of Congress, attached riders to appropriations bills barring the use of the money for the promised payments.

The arc of partisanship in impeachment, to some extent, matches the increased polarization of politics in America over the last 45 years. It moves from consensus to deadlock.

When the House Judiciary Committee votes on articles of impeachment against President Trump, the vote is expected to be along purely partisan lines — a far cry from the committee impeachment vote against President Richard Nixon in 1974, and different too from the President Bill Clinton's impeachment in 1998.

Guns: when and how to regulate them. It's one of the biggest issues across the country. But the U.S. Supreme Court has rarely weighed in on the issue. In modern times, it has ruled decisively just twice. Now it's on the brink of doing so again.

With the retirement of Justice Anthony Kennedy, there now are five conservative justices who may be willing to shut down many attempts at regulation, just as the NRA's lock on state legislatures may be waning.

A vast hall filled with members of the conservative Federalist Society on Thursday night welcomed Supreme Court Justice Brett Kavanaugh as a conquering hero, while outside on a large screen protesters played video from Kavanaugh's confirmation hearing of testimony by Christine Blasey Ford, the woman who accused him of sexual misconduct.

The U.S. Supreme Court's conservative majority signaled Tuesday that it may let the Trump administration shut down the Obama-era program that granted temporary protection from deportation to roughly 700,000 young people, commonly known as DREAMers.

Brought to the U.S. illegally as children, the DREAMers were allowed to legally work and go to school if they met certain requirements and passed a background check. The program, begun in 2012, is known as DACA — Deferred Action for Childhood Arrivals.

The U.S. Supreme Court hears arguments Tuesday in a highly anticipated set of cases that threatens the legal status of some 700,000 young immigrants — often called DREAMers — who were brought to the U.S. illegally as children. It's a program that President Trump tried to rescind seven months after taking office, only to have the lower courts block his action.

Mitchell Santos Toledo came to the United States when he was 2. His parents had temporary visas when they brought him and his 5-year-old sister to the country. They never left. This spring, Santos Toledo will graduate from Harvard Law School. He is one of the 700,000 DREAMers whose fate in the U.S. may well be determined by a Supreme Court case to be argued Tuesday.
