9/11 anniversary sparks renewed warnings about US homeland security from lawmakers

More than two decades after the 9/11 attacks, lawmakers are urging the federal government to remain vigilant and continue efforts to bolster national security to prevent future terrorist attacks.

Although lawmakers largely agree the U.S. government has taken significant steps to improve its safety and attack prevention, such as the creation of the Department of Homeland Security following the 9/11 attacks, many noted the country must stay on guard as some foreign countries engage in warfare overseas.
