Attorney General Jeff Sessions Wednesday defended the travel bans issued by the Trump administration, telling the Senate Judiciary Committee he was "confident" the ban would prevail.

"The president's executive order is an important step to ensuring that we know who is coming into our country," Sessions told the committee. "It is a lawful, necessary … order that we are proud to defend and indeed most may not know the Supreme Court has already vacated one court's injunction against that order and we are confident we'll prevail as time goes by in the Supreme Court."

The remarks Wednesday were part of Sessions' opening statements at his first appearance before the committee for an oversight hearing since he took over the Department of Justice.

President Trump's travel bans have faced nearly continuous legal action since the first one was launched in January, which also led to protests at airports around the country as the ban was placed on nations with Muslim-majority populations.

Most recently, the latest iteration of the ban was shot down by a federal judge in Maryland on Wednesday morning and a Hawaii federal judge on Tuesday.

The Supreme Court was originally going to examine the original travel ban this fall, but took the travel ban cases off its calendar after the existing executive order's expiration date passed and the Trump administration developed a new order and new guidance.

Between the opening statements of committee Chairman Chuck Grassley, R-Iowa, and Vice Chairman Dianne Feinstein, D-Calif., the hearing was set up to move over a broad range of issues, including topics as wide-ranging as nationwide increases in crime, the use of "bump stocks" on firearms, the Deferred Action for Childhood Arrivals program, voter access, as well as the president's travel ban.
