Alabama Sen. Tommy Tuberville, under fire for his months-long hold on military promotions as a protest for a new Pentagon policy on abortion services in the military, raised the point Monday that his strategy is not as novel as some have portrayed.

In 2020, Sen. Tammy Duckworth, a decorated Iraq war veteran and senator from Illinois, invoked a similar hold in protest.

Tuberville on Monday tweeted a three-year-old press release from Duckworth announcing her hold of more than 1,200 promotions. Duckworth demanded that former Defense Secretary Mark Esper confirm in writing that he did not block the promotion of Lt. Col. Alexander Vindman to colonel. Vindman, then the Ukraine expert during the Trump administration, listened to and reported his concerns about the call former President Donald Trump had with Ukraine President Volodymyr Zelenskyy.

The House of Representatives eventually impeached Trump over the phone call, in which he asked Zelenskyy to publicly announce an investigation into then-presidential candidate Joe Biden and his son, Hunter, in exchange for military aid.

Vindman eventually retired, having never been promoted to colonel.

Duckworth lifted her hold after two weeks after receiving assurances Vindman received no promotion backlash as a result of reporting the Ukraine phone call.

Three years later, Duckworth blasted Tuberville for his hold on military promotions. Tuberville is objecting to the policy providing paid leave and travel expenses for servicewomen to receive abortions in the aftermath of the Supreme Court last year returning the issue of abortion rights to the states. Tuberville said he will lift his hold if Congress votes to approve the policy or if the policy is rescinded.

Asked during an appearance Sunday on NBC’s Meet the Press if she was willing to put a vote on the issue in the Senate, Duckworth said “We’ve given him (Tuberville) many options for a vote, and he’s turned them all down. Joni Ernst (Republican U.S. senator from Iowa) has a bill that goes even further than where Senator Tuberville is, and he declined that vote.

“And Republican leadership had offered him multiple off-ramps to this,” Duckworth said. “And he’s backed himself into a corner, I mean. You know what he’s saying is that Democrats need to pass a national codification of Roe V Wade. We would love to do that. Obviously, that’s not going happen anytime soon with the Senate as closely split as it is,” she said.

“I’m going to just say what President Biden has said. It is bizarre for Senator Tuberville to say that he’s not jeopardizing national security when he injects politics into the defense process,” Duckworth said.

In another tweet Monday, Tuberville said, “I didn’t start this. (Biden) injected politics into our military and imposed taxpayer funding of abortion that nobody voted for. I am trying to get politics out of the military.”

And in retweeting Duckworth’s post of her op/ed on MSNBC criticizing Tuberville, the Alabama senator said, “This is not about abortion. This is about taxpayer-funded abortion that Congress NEVER authorized.”

While tax money does not fund the abortion itself, it does provide funds for paid leave and travel expenses.
