HONOLULU — Renewing his emphasis on the need for more gun restrictions, President Obama will participate in a live televised town-hall-style meeting on Thursday to discuss gun violence in the United States, according to the White House.

The hourlong event, at George Mason University outside Washington, will be televised on CNN at 8 p.m. On Monday, Mr. Obama will meet with Attorney General Loretta E. Lynch to discuss what executive actions he can take to curb gun violence.

After the shootings that killed 14 people in San Bernardino, Calif., on Dec. 2, Mr. Obama’s initial response focused on the need for gun restrictions. The administration soon realized, however, that this message had not reassured many Americans that the president was sufficiently addressing the Islamic State, the extremist group that inspired that attack and carried out one in Paris in November that left 130 people dead.

So, through much of December, Mr. Obama took part in a series of public events in an effort to convince the nation that his administration was doing everything it could to battle the Islamic State, also known as ISIS or ISIL.
