Republican questions about how and when changes were made to his administration's "talking points" about last September's attack on the U.S. Consulate in Benghazi, Libya, are a "sideshow," President Obama told reporters at the White House on Monday.

"There's no there, there," the president declared.

"What we have been clear about throughout," Obama insisted, is that "we were not clear who exactly had carried this out."

James Holmes on Monday formally changed his plea from not guilty to "not guilty by reason of insanity" for the July 20, 2012, movie theater shooting rampage in Aurora, Colo., that left 12 people dead and an additional 70 injured.

Holmes' lawyers had said last week that the young man would be doing this.

It's "outrageous and there's no place for it" if the Internal Revenue Service did, as it has admitted, single out some conservative groups for extra scrutiny in recent years, President Obama said Monday morning during a news conference at the White House.

A unanimous Supreme Court ruled Monday that an Indiana farmer infringed on Monsanto's patent when he planted soybeans that had been genetically modified by Monsanto without buying them from the agribusiness giant.

"The Internal Revenue Service's scrutiny of conservative groups went beyond those with 'tea party' or 'patriot' in their names — as the agency admitted Friday — to also include ones worried about government spending, debt or taxes, and even ones that lobbied to 'make America a better place to live,' " The Wall Street Journal reports.

U.S. Secretary of State John Kerry "made a real breakthrough" last week in talks with Russian President Vladimir Putin when they agreed there will be an American-Russian peace conference on Syria, British Prime Minister David Cameron told NPR on Monday.

Calling his brother a hateful monster, Onil Castro has told CNN he hopes Ariel Castro "rots in that jail."

"I want him to suffer," he said of Ariel, the 52-year-old man accused of holding three young women captive in his Cleveland home for about a decade — years in which Ariel Castro allegedly raped them repeatedly and subjected them to other physical and mental torment.

With a commanding lead for his party in the vote count following Saturday's parliamentary elections, former Pakistani Prime Minister Nawaz Sharif is returning to power with a clear mandate to focus on the grave problems facing his nation, as NPR's Julie McCarthy reports from Lahore for Morning Edition.

Until today, there's been a rush of news related to the kidnapping of three young women in Cleveland, their rescue after a decade in captivity and the chilling details that have emerged about what they went through. Now, the news has slowed. We suspect there will be less to report in coming days, but we'll watch for important developments.

There is a story to recommend, though:

The news that Boston Marathon bombings suspect Tamerlan Tsarnaev has been buried in a rural cemetery just north of Richmond, Va., is causing controversy there.

Despite attacks in the days and weeks leading up to Saturday's voting — and deadly bombings and other attacks on the very day they're going to the polls — Pakistanis are showing they're willing to "defy the violence," NPR's Julie McCarthy reports from Lahore.

The same scientist who famously "killed Pluto" (as a planet, that is) says it's "brilliant" that there's an effort underway in Congress to name a science laureate.

Two astronauts went on a last-minute spacewalk Saturday to replace a pump suspected of being the source of a serious ammonia leak.

It was unclear what caused the ammonia leak, NASA spokesman Rob Navias said, "but the installation of this spare pump package — at least at the moment — seems to have done the trick."

NASA officials called the spacewalk a success, but said it would take time to see if the leak was indeed stopped. Engineers will review photos the astronauts took at the site.

Saturday's reports about the arrest of a former emergency services volunteer in the town of West, Texas, indicate the story has not moved much from where we left things on Friday:

Former Guatemalan dictator Efrain Rios Montt was convicted of genocide by a court in his country Friday for the part he played in massacres and other crimes committed against Mayans while he ruled in 1982 and 1983.
