Executive order to expand firearm background checks signed amid ongoing challenge of passing stricter US gun laws.

Biden underscored his commitment to further regulate guns in an announcement on Tuesday before he is expected to visit the California community of Monterey Park, where a gunman stormed a dance hall and killed 11 people in January.

“Every few days in the United States, we mourn a new mass shooting,” Biden said in the order.

“We cannot accept these facts as the enduring reality of life in America,” the order said. “Instead, we must together insist that we have had enough.”

The executive order aims to expand background checks and increase public awareness of so-called “red flag laws”, which are meant to keep guns out of the hands of people displaying troubling behaviour that is reported to law enforcement by family or friends.

It also calls for the Federal Trade Commission to investigate the methods gun manufacturers use to market firearms to minors and civilians, including the use of military imagery in their campaigns.

Biden’s order builds on previous legislation the president signed in June that included similar measures and a provision barring those convicted of domestic violence from purchasing firearms if they are still involved with the victim.

The announcement on Tuesday called last year’s law, which followed a shooting at an elementary school in Uvalde, Texas in which 19 children and two staff members were killed, “the most significant gun violence reduction legislation enacted in nearly 30 years”.

However, some observers have pointed out that the legislation did little to substantially decrease firearms access in the US.

It also did not include restrictions on assault-style rifles that have been used in numerous mass shootings, which Biden has said he would like to see banned.

“As he continues to call on Congress to act, President Biden will do everything he can to reduce gun violence and save lives,” the White House said in a statement detailing Tuesday’s executive order.

A Reuters/Ipsos poll last year found 84 percent of respondents supported background checks for all firearms sales and 70 percent backed red flag laws.

Some gun rights advocates oppose background checks, saying they infringe on the constitutional right to possess arms while failing to stop criminals from getting them. They also contend many red flag laws trample on due process rights.

Republican legislators are largely hostile to attempts to enact more comprehensive gun control legislation, and the conservative majority in the US Supreme Court has struck down gun laws in Democrat-governed states such as New York.

The White House seemed to acknowledge those challenges on Tuesday, stating that the measures contained in Biden’s executive order would move the US “as close to universal background checks as possible without additional legislation”.
