CLEVELAND, Ohio — The Republican National Convention is in full swing and delegates are set to nominate Donald J. Trump for President later this week. But before the big reveal and balloon drop, the convention stage will serve as a pedestal displaying the GOP’s political talent and leadership from across the country. Dozens of high profile leaders will take the stage to advocate for Trump and the GOP, including celebrities, entertainers and members of Trump’s family. But on Monday night, the world will stop to hear from Alabama’s own Jeff Sessions, who became the first U.S. senator to endorse the billionaire real estate mogul back in February.

Sessions will headline Monday’s festivities which are themed, “Make America Safe Again.” Each night of the convention will feature a different focus, but Sessions taking the lead on the law and order portion of the program comes as no surprise.

Here’s how the RNC explained Monday’s “Make America Safe Again” theme:

From attacks on our own soil and overseas to the tragedy in Benghazi, the policies of Barack Obama and Hillary Clinton have left us vulnerable. Our immigration system is broken, leaving our country open to security threats and the negative consequences of illegal immigration. A Donald Trump administration will listen to and learn from our nation’s heroes who have put themselves in harm’s way and pursue a national security strategy and foreign policy that will strengthen our military and make America safe again.

Sessions has been instrumental in Trump’s campaign for months. After his endorsement of the New York Billionaire, Alabama’s junior senator was named the head of Trump’s national security advisory committee.

Sessions has long been one of the most outspoken members of Congress on several key national security issues, chiefly immigration. Most recently, Sessions pushed legislation to punish sanctuary cities, which harbor illegal immigrants against federal law.

The Senate will soon take a vote on “Kate’s Law” which would guarantee a five-year prison sentence for illegal immigrants who cross back into the U.S. after being deported. If passed, the law would crack down on sanctuary cities like San Francisco that harbor such individuals.

Sessions and others in Alabama’s congressional delegation have fought the Obama Administration’s effort to resettle refugees and immigrants in the Yellowhammer State. A Sessions-led Senate committee recently estimated Mrs. Clinton’s refugee resettlement plan would cost upwards of $400 billion.

In light of the current climate for law enforcement, Sessions has also introduced more legislation to protect those who protect everyday Americans. Senator Sessions has partnered with Sen. Pat Toomey (R-Pa.) to introduce the Thin Blue Line Act, which would enforce harsher penalties on individuals targeting police officers and first responders. Sessions worked closely with federal, state and local law enforcement officials for years as Alabama Attorney General and before that as a U.S. Attorney.

Sessions is likely to talk about all of these topics and more in his national security-related speech this evening.
Sessions will be joined with some other heavy-hitters on Monday, including former Texas Governor Rick Perry, Duck Dynasty star Willie Robertson, former New York Mayor Rudy Giuliani, Ivanka Trump, and Marcus Luttrell.
