A top Senate Republican wants answers on why the Biden administration drained the nation’s oil stockpile but did little to replenish it.

Sen. Tom Cotton, R-Ark., charged that decisions under President Joe Biden to tap the Strategic Petroleum Reserve (SPR) could have a ripple effect as the U.S. continues its war with Iran and as the Iranian government continues its chokehold on the Strait of Hormuz.

Cotton, in a letter first obtained by Fox News Digital to Department of Energy Secretary Chris Wright, charged that the Biden administration released 180 million barrels from the nation’s reserves in 2022 ‘to suppress gas prices ahead of the midterm elections.’

‘That decision drained the reserve to a 40-year low,’ Cotton wrote. ‘The decision to drain the SPR was not a response to a supply emergency; it was a deliberate political act designed to protect Democrats from the consequences of their own failed energy policies.’

Biden tapped the reserve twice — once in 2021 to relieve soaring fuel prices as the nation still grappled with the economic fallout from the COVID-19 pandemic and again the following year to combat increased energy costs at the onset of the war between Russia and Ukraine.

The SPR has capacity for over 700 million barrels of crude oil, but currently, the reserve has far less following the drawdown under the previous administration.

At the end of Biden’s term, the reserve had about 415 million barrels of crude on hand, according to data from the Department of Energy.

Cotton said that it wasn’t ‘the first time Democrats undermined the reserve’ and noted that Senate Minority Leader Chuck Schumer, D-N.Y., and congressional Democrats blocked President Donald Trump’s bid to refill the SPR in 2020, when barrels were cheap, with $3 billion from a colossal COVID-19 stimulus package moving through Congress.

He also said that in 2021, Biden signed an executive order that halted new oil and gas leases on federal lands and offshore, which Cotton charged ‘constrained domestic production while the administration was draining the reserve.’

Cotton demanded that Wright answer how blocking the $3 billion oil purchase and halting oil and gas leases impacted the nation’s overall domestic supplies that could have been used to replenish the SPR.

Meanwhile, congressional Democrats are demanding that Trump tap into the SPR after oil prices spiked to four-year highs over the weekend as the war in Iran intensifies.

Schumer said that the reserve ‘exists for moments exactly like this.’

‘The Strait of Hormuz is the world’s most important oil transit choke point, with roughly 20% of global petroleum liquids consumption moving through it in recent years,’ Cotton said. ‘That is precisely why the SPR must be treated as a strategic national security asset, not a political tool.’

Jeremy Carl, President Donald Trump’s nominee for assistant secretary of state for international organization affairs, withdrew his nomination Tuesday after facing bipartisan criticism over past comments about race, religion and Israel.

Carl, a conservative commentator and senior fellow at the Claremont Institute, wrote on X that he lacked the unanimous Republican support needed to advance his nomination out of the Senate Foreign Relations Committee. He was nominated to the State Department role by President Donald Trump and Secretary of State Marco Rubio.

‘I am withdrawing my nomination for consideration as Assistant Secretary of State for International Organization Affairs,’ he wrote Tuesday afternoon. ‘I am tremendously grateful to President Trump for nominating me and then (upon expiration of my original nomination) renominating me for this role, and I am also grateful to Secretary Rubio and his team for their continued support throughout this long and time-consuming process.’

Republicans hold a 12-10 majority on the panel, meaning a single GOP defection would result in a tie vote and block the nomination from moving to the full Senate.

‘Unfortunately, at this time this unanimous support was not forthcoming,’ Carl wrote, adding that he did not want the administration to ‘waste valuable time and energy’ attempting to change the outcome.

During his confirmation hearing last month, senators pressed Carl on previous remarks concerning ‘white identity,’ immigration and Israel. Sen. John Curtis, R-Utah, specifically pressed him on an October 2024 podcast, in which Carl said, ‘the United States spends too much time and energy on Israel, often to the detriment of our own national interests.’ Curtis challenged Carl on what American interests were harmed, and asked if he recognized the benefits that the U.S. gains from the relationship with Israel. Carl dodged the questions, but did say that he wishes that ‘the UN would stop being antisemitic all the time.’

Curtis also cited the same podcast, in which the host accused Jews of claiming a ‘special victim status’ over the Holocaust, and said, ‘Israel is not a victim, but instead a perpetrator,’ to which Carl responded, ‘Right, right. Yeah, no, I mean, I think that’s true.’ Carl at first said that he would have to review the question, but when Curtis noted that he gave Carl’s exact words, Carl admitted, ‘I’m sure that they’re accurate.’

Curtis said afterward that Carl was not the ‘right person to represent our nation’s best interests in international forums.’

Sen. Chris Murphy, D-Conn., questioned Carl about his references to ‘white identity’ and what he believed was being ‘erased.’ Carl responded that he was concerned about the erosion of what he described as a majority American culture due to mass immigration, saying he stood by those comments. Murphy later called him a ‘legit white nationalist’ on social media.

Carl rejected that characterization, saying he is ‘not a White nationalist’ and that his remarks referred to a broadly shared American culture that people of all backgrounds could embrace.

‘Unfortunately, for senior positions such as this one, the support of the President and Secretary of State is very important but not sufficient,’ Carl added on X. ‘We also needed the unanimous support of every GOP Senator on the Committee on Foreign Relations, given the unanimous opposition of Senate Democrats to my candidacy, and unfortunately, at this time this unanimous support was not forthcoming.’

The position Carl was nominated to oversees U.S. engagement at the United Nations and other multilateral organizations. He previously served as a deputy assistant interior secretary during Trump’s first term.

‘I remain extremely confident in President Trump, Secretary Rubio, and the rest of the outstanding team at State (a group of leaders that includes many close friends),’ Carl concluded on X. ‘I know they will continue to pursue a foreign policy that puts America first, and that they will work to ensure America is able to exercise its power and influence in the world like never before.’

Fox News Digital reached out to the White House and the State Department for comment and has not heard back.
