The prosecution's star witness underwent a withering cross-examination on Thursday at Roger Clemens' perjury trial. Clemens, a seven-time Cy Young Award winner, is charged with lying to Congress when he testified that he never used performance-enhancing drugs. Brian McNamee, his one-time trainer, is the only witness who has firsthand evidence that contradicts the baseball-pitching ace.

Earlier this week, guided by the prosecution, McNamee testified in agonizing and repetitive detail about how he injected Clemens with steroids and human growth hormone between 1998 and 2001.

My father, world-renowned virtuoso violinist and teacher Roman Totenberg, whose professional career spanned nine decades and four continents, died early Tuesday morning at the age of 101.

His death was as remarkable as his life. He made his debut as a soloist with the Warsaw Philharmonic at age 11, performed his last concert when he was in his mid-90s, and was still teaching, literally, on his deathbed. This week, as word flew around the musical world that he was in renal failure, former students flocked to his home in Newton, Mass., to see the beloved "maestro."

The prosecution at the perjury trial of baseball great Roger Clemens suffered another major setback Wednesday. One of its key witnesses, pitcher Andy Pettitte, conceded that he may have misunderstood his former teammate as saying he used human growth hormone (HGH).

Clemens is charged with lying to Congress when he testified before a House committee that he had never used performance-enhancing drugs.

If the prosecution at the Roger Clemens perjury trial hoped for a dramatic showdown on Tuesday, the day was a big disappointment. The prosecution's star witness, Clemens' friend and onetime pitching ace Andy Pettitte, provided as much, if not more, ammunition for the defense.

Clemens is charged with lying to Congress when he testified that he had never used performance-enhancing drugs.

A majority of U.S. Supreme Court justices signaled Wednesday that they will uphold at least part of Arizona's controversial immigration law. Four provisions of the law were blocked by a federal appeals court last year, and while even some of the court's conservatives expressed skepticism about some of those provisions, a majority seemed willing to unblock the so-called "show me your papers" provisions.

The U.S. Supreme Court takes up yet another incendiary election issue Wednesday when it hears arguments on a controversial Arizona law that targets illegal immigrants.

As with last month's test of the Obama health care overhaul, the case pits the federal government's assertion of power against some states, and with some exceptions, it pits Democrats against Republicans.

The retrial of baseball great Roger Clemens began in earnest Monday after a week of jury selection. Clemens is charged with lying in 2008 to a congressional committee when he denied ever using steroids or human growth hormone.

He will be judged by a jury of 10 women and 6 men — 12 jurors and 4 alternates — who will decide whether Clemens lied under oath about using the drugs when he testified before a congressional committee investigating the use of performance-enhancing drugs in baseball.

The U.S. Supreme Court has ruled unanimously that organizations cannot be sued for the torture under the Torture Victim Protection Act.

Baseball star Roger Clemens goes on trial for a second time Monday on charges that he lied to a congressional committee about using steroids and human growth hormone. His trial on perjury and obstruction charges last summer ended abruptly when prosecutors mistakenly showed the jury evidence that the judge had ruled inadmissible.

Clemens won a record seven Cy Young awards during his storied pitching career, but prosecutors contend that he used steroids and human growth hormone to prolong that career.
