Speaker Mike Johnson, R.-La., is forging ahead with his latest proposal to renew a key American spy power. His bill, revealed Thursday, is largely unchanged from a previous plan which failed in a series of overnight votes earlier this month.

The program at center of the debate, Section 702 of the Foreign Intelligence Surveillance Act (FISA), is set to expire on April 30.

FISA 702 allows U.S. intelligence agencies to intercept the electronic communications of foreign nationals located outside of the United States. Some of the nearly 350,000 foreign targets whose communications are collected under the provision are in touch with Americans, whose calls, texts and emails could end up in the trove of information available to the federal government for review.
