Is Sen. Dan Sullivan in the running for Donald Trump‘s second in command? You betcha!

The junior senator, whose name is the latest to bubble up among PEOPLE’s GOP sources monitoring the Trump ‘veepstakes,’ isn’t a “mama grizzly” or a hockey mom, but he just might be the latest representative of Alaska to enter the presidential race, following fellow Alaskan Sarah Palin.

As the veepstakes continue – Iowa Sen. Joni Ernst has met with Trump, as well as Indiana Gov. Mike Pence, and Arkansas Sen. Tom Cotton got some online praise from the presumptive nominee – here’s everything you need to know about Sullivan, 51.

1. He was Alaska’s Attorney General
Before being sworn in on January 6, 2015, Sullivan served as the Commissioner of the Alaska Department of Natural resources until 2013.

Prior to that, he was Alaska’s Attorney General from 2009 to 2010, spearheading the “Choose Respect” campaign geared toward eliminating the state’s high rates of domestic assault and violence, according to his website.

2. He’s a Marine
Sullivan, a Harvard and Georgetown graduate, joined the Marine Corps in 1993, eventually leaving active duty in 1997. He is now a member of the United States Marine Corps Reserve, and was called to active duty three times: from 2004 to 2006, in 2009 and for six weeks in 2013, according to the Alaska Dispatch News.

That year, he was also selected to command the Air Naval Gunfire Liaison Co. reserve unit, which is California-based, ADN said.

3. He’s a father of three

Sullivan met his wife Julie in 1990 while he was in law school at Georgetown, ADN reported.

Now married for more than two decades, the pair have three teenage daughters: Laurel, Isabella and Meghan.

4. He’s an avid fisherman – and supports them in Congress
Julie’s family owns a fish camp, a favorite escape for Sullivan.

“He just fell in love with it,” she told ADN.

And the sportsman is supporting fishermen in Congress, too, according to Alaska news outlet Capital City Weekly. One bill spearheaded by Sullivan – which recently passed out of the Senate Commerce committee – will help outline strict guidelines recently set about for fishing vessels.

Another will require the nation’s school lunch program to purchase seafood from American producers.

5. He’s not afraid to hold Trump accountable
Weighing in on Trump’s controversial comments about U.S. District Judge Gonzalo Curiel, Sullivan told MSNBC, “When Donald Trump makes statements that we disagree with, we speak out. I certainly have been one to be critical, certainly the comments were completely wrong.”

“He has two paths: which is continue these self-inflicted wounds … or pivot to the issues that Americans care about.”

He added, “When Donald Trump makes statements that I think are offensive or even policy statements that I disagree with, I’m somebody who has come out and been very clear, very direct with how I view those.”
