Oklahoma Congressman Markwayne Mullin is heading home, but where he's been and what exactly he's been doing, has some members of the federal government asking a lot of questions.

Mullin, who represents Oklahoma's second congressional district, made national headlines Tuesday night after reports that he was trying to rescue five American citizens stuck in Afghanistan.

According to the Washington Post, Mullin has been in Greece and the country of Georgia over the past few days, trying to work with the US Ambassador to Tajikistan to hire a helicopter to rescue the family.

The Washington Post said his request was denied, but U.S. officials were unsure of his exact location.

On Wednesday, Mullin posted on Instagram confirming he is helping get Americans out of Afghanistan, but said he was never missing

He also said he's heading home, but his mission continues.

This all comes as Mullin, like many Republicans, have been very critical of President Biden's withdrawal from Afghanistan calling him a liar and tweeting on Monday, "This is a sad day for our country..." and "One motto of our military is 'leave no man behind.' But today, that's exactly what President Biden did."

Mullin is not the first Congressman to try and make unauthorized trips to Afghanistan recently. Democrat Seth Moulton and Republican Peter Meijer both traveled to the country recently.

"If I could get on a plane and save a few more lives, then absolutely I'll do that," said Moulton to CBS News.

The White House though said they are not supporting any of these trips.

"This is not the time to travel to Afghanistan," said Jen Psaki, White House Press Secretary.

The Oklahoma Democratic Party released a statement about Mullin’s trip. They call it "a ridiculous publicity stunt".
