Seventy-three percent of all those convicted with international terrorism-related charges in U.S. federal courts between Sept. 11, 2001 and Dec. 31, 2016 were foreign-born, Homeland Security Secretary Kirstjen Nielsen told "CBS This Morning" on Tuesday.

Nielsen, who was citing a new report created by the Department of Homeland Security and the Department of Justice, is scheduled to testify on Tuesday in front of the Senate Judiciary Committee on the study.

Nielsen said the report "underscores the need to not only implement the executive orders that [the president has] issued over the past year, but I feel very strongly about going to Congress today during a hearing and work with them to close the loopholes that prevent us from removing known, suspected terrorists and other criminals in the United States."

The secretary specifically said we need to not only "continue to enhance our screening and vetting, but ... also to continually vet those who are here. We have examples unfortunately over the last decades of terrorist attacks from legal permanent residents and others who were naturalized. So we need to be able to continue up until the point they become a U.S. citizen, to continue to vet them to ensure they haven't become radicalized."

Nielsen emphasized that constantly checking legal residents should be "a very natural part of becoming a citizen. Up until the point that you're a citizen, we wanna continue to make sure we understand who you are and why you're here."

The report comes on the heels of recent terror-related offenses allegedly committed by those born abroad who had legally immigrated to the U.S., according to The Daily Caller.

Examples of such attacks are two separate incidents in New York City — a deadly truck rampage in October and an attempted suicide bombing in December.
