“Thank God for President Trump coming in and empowering us to enforce our nation’s laws. We’re able to see the crime rate drop, we’re able to see murder rates drop to a 126-year low, we’re seeing violent crimes drop to 30-40 year lows, and we’re seeing fentanyl overdoses go backward for the first time because we’re enforcing our nation’s laws.” @SecMullinDHS

@SecMullinDHS on the importance partnerships played in the MASSIVE @ICEgov Lone Star Mission that led to the arrest of over 4,100+ illegal aliens in just 10 days.
"Here in Texas they're protecting their state...thank you for the cooperation that we had from our partners from state, local, and county, it's not possible to do it without your help."

Democrats allowed millions of illegal aliens, including murderers, pedophiles, gang members, & suspected terrorists, to pour into America.
On day one, President Trump secured the border & stopped the invasion.
WORST OF THE WORST ARRESTED IN SOUTH CAROLINA ⬇️
The patriots of @ICEgov are hard at work every single day across America, including in South Carolina to undo the damage from four long years of Biden’s open borders.
Arresting and deporting killers, violent assailants, burglars, and drug traffickers like these is how we protect our communities, save lives, and make America safe again. 🧵
Luis Osorio, an illegal alien from El Salvador, arrested by ICE in Columbia, South Carolina, on October 27. His criminal history includes a conviction for trafficking cocaine – 28 grams or more.
President Trump promised the American people that our immigration laws would be enforced, and these numbers reflect the scale of that commitment.
Those who abuse or flagrantly disregard our immigration system are now on notice that these violations of law will not be tolerated or overlooked.
Securing our border was only the beginning. We are restoring integrity to the entire immigration system and putting the safety of our American citizens first.
Protecting American soil means knowing who is coming into our country.
Visa-free travel to the Commonwealth of the Northern Mariana Islands opened the door to Chinese birth tourism and national security threats.
Under President Trump’s leadership, we’re putting a stop to the Economic Vitality & Security Travel Authorization Program and putting the American people first. American citizenship is not a travel perk.

Together with America’s First Responders, we’ve achieved the most secure border in history, slashed fentanyl across the southern border, driven crime to historic lows, & Made America Safe Again.
To every fearless first responder hero who answers the call every day, THANK YOU 🇺🇸
This illegal alien from Guinea was arrested for assaulting a police officer with a deadly weapon. Despite these violent charges, New York City sanctuary politicians refused to honor ICE’s detainer and RELEASED him back onto the streets, and he remains at large.
This is the vision of sanctuary politicians in a nutshell: the open-border policies of the Biden Administration let this criminal into our country, and then sanctuary politicians in New York released him after arresting him without notifying ICE. @DHSGov is calling on Governor Kathy Hochul and Mayor Zohran Mamdani to knock it off with these evil sanctuary policies before another American gets hurt, or worse.
MANHUNT UNDERWAY: An illegal immigrant from Guinea accused of assaulting a police officer with a deadly weapon is on the loose after New York City ignored two separate ICE detainer requests and released him back onto the streets.
Alpha Bah was arrested on Oct. 7 for aggravated assault on a police officer with a deadly weapon, resisting arrest, and obstructing governmental administration. ICE lodged a detainer — NYPD released him anyway.
DHS Secretary Markwayne Mullin is calling on Gov. Kathy Hochul and Mayor Zohran Mamdani to reverse their sanctuary policies, warning that another American could get hurt "or worse."

Under President Trump’s leadership, we are not going to let companies tied to forced labor and the surveillance of persecuted minorities profit from the American market.
Today, @DHSgov is barring three Chinese DNA testing companies from allowing their goods to enter the United States unless importers can meet the law’s requirements.
This is about enforcing our laws, protecting American businesses from unfair competition, and making clear that companies connected to forced labor will not get a free pass in this country.

"President Trump has made it very clear he can secure the border. It was Biden who said he needed Congress to act. We didn’t need Congress to act; we needed a new president. Because of President Trump’s leadership, we do have a secure border, and we can now concentrate on inner cities. You’re seeing crime rates drop because of the enforcement that President Trump has tasked the Department of Homeland Security with." @SecMullinDHS

"You put yourself in the place of these angel families, and you go, “Why?” And the Biden administration pushed them to the side and didn’t even want their stories to be heard. Their stories should be heard. One hundred percent of these deaths were preventable because none of those individuals should have been in the country to begin with. It breaks your heart." @SecMullinDHS

.@SecMullinDHS: You’re seeing crime rates drop because @POTUS has tasked @DHS with taking these worst-of-the-worst criminals off our streets. Murder rates have dropped to a 126-year low. Violent crime has dropped to a 30-40-year low.
