NEW YORK — Senator Charles Schumer plans to introduce legislation requiring a $25,000 reward for information generated through social media that helps thwart a terrorist attack.

The New York Democrat, who formally announced the bill at a news conference Sunday, said the legislation would be introduced this month.

He said the public should ‘‘say something if they see something, especially on their newsfeed.’’

Schumer said current law does not specifically cover tips generated through social media. The proposed bill would require the State Department to pay rewards of no less than $25,000 for information that leads to an arrest or conviction in a terror case.

In an interview with Fox News that was broadcast Sunday, President Obama said he doesn’t think Americans have overreacted to the threat of terrorist attacks.

But Obama also said he hasn’t let acts of terror disrupt some of his regular activities because it’s important to communicate a message of resilience and ‘‘that we don’t panic, that we don’t fear.’’

Obama defended his administration’s efforts to stop the international terror threat.

“My No. 1 job is to protect the American people,’’ Obama said, in the interview taped Friday. “My No. 1 priority right now is defeating’’ the Islamic State.
