President Obama had a reputation when he took office as a liberal former constitutional lawyer who had condemned Bush-era national security policies.

But he has proven to be even tougher than President George W. Bush on prosecuting national security leaks. The seizure of Associated Press phone records is just the latest example.

President Obama has spoken at two memorial services in just over a week — one for victims of the Boston Marathon attack and one for those who died in the chemical plant explosions in West, Texas. In both speeches, he focused on victims and survivors.

But other Democrats are using these events to talk about another subject: the role of government.

President Obama's time in office has not been defined by terrorism as President George W. Bush's was. Yet incidents like the one in Boston have been a regular, painful through line of his presidency.

When a new administration walks into the White House, nobody provides a handbook on how to respond to a terrorist attack. So the Obama administration has been on a steady learning curve.

Now, President Obama had promised to put the full weight of his office behind getting Congress to pass new gun control legislation. That weight was apparently not enough. When the legislation failed yesterday, Obama went into the White House Rose Garden and made a blistering speech, calling it a shameful day for Washington.

NPR's Ari Shapiro was there.

From Boston now to the White House, where President Obama reacted angrily tonight to the failure of an effort in the Senate to expand background checks for gun purchases. The amendment, proposed by Democrat Joe Manchin and Republican Pat Toomey, got only 54 votes - six short of the necessary 60. President Obama spoke in the White House Rose Garden. He called this a pretty shameful day for Washington.

This week marked a new step in Michelle Obama's evolution as first lady. In her hometown of Chicago, she delivered one of the most emotional speeches of her career — about kids dying from gun violence.

"I'm not talking about something that's happening in a war zone halfway around the world," she said. "I am talking about what's happening in the city that we call home."

Republicans don't often make high-profile speeches at Howard University, one of the country's most prominent historically black schools. But on Wednesday, Kentucky Sen. Rand Paul will talk to Howard students about how his party can be more inclusive.

Paul believes one answer is libertarianism — and party leaders are starting to think he might be on to something.

The Republican and Democratic parties have been in a digital arms race for years. And this week, Republicans frankly admitted that they are losing.

Now, the GOP has ambitious plans to improve its game.

Monday's report from the Republican National Committee puts it bluntly: "Republicans must catch up on how we utilize technology in our campaigns. The Obama team is several years ahead of everyone else in its technological advantage."

After the attacks of Sept. 11, 2001, President George W. Bush often made a provocative claim: He argued that the U.S. was fighting a war without a typical battlefield. In effect, he said, this war is everywhere.

"Our enemies make no distinction based on borders," he said in a 2007 speech in Michigan. "They view the world as a giant battlefield and will strike wherever they can."

Sequestration is official. President Obama signed an executive order on spending late last night as required by law. He sent the order to Congress and that triggered budget cuts known as sequestration. Earlier in the day, the president met with congressional leaders and when they left without a deal, he took questions at the White House.

NPR's Ari Shapiro was there.

The country has been debating gun regulations for months. Later this week, a Senate committee will start work on various proposals, including a background check on every gun sale and a ban on assault weapons.

But this debate over guns goes beyond disagreements about policy. Advocates on both sides quite literally disagree on the terms of the discussion — as in, the words they use to describe it.

Ask "gun control advocates" to describe what this debate is about, and they'll say "control" really isn't the word they prefer.
