Did Biden Once Say that Trump Didn't Have Authority for War with Iran Without Congress' Approval?

"A president should never take this nation to war without the informed consent of the American people," part of the purported quote read.

On Jan. 6, 2020, a post on then-Democratic presidential hopeful Joe Biden's personal Twitter account read, "Let's be clear: Donald Trump does not have the authority to take us into war with Iran without Congressional approval. A president should never take this nation to war without the informed consent of the American people."

In January 2024, Republican U.S. Rep. Marjorie Taylor Greene posted an image of a post that looked to have been sourced from U.S. President Joe Biden's personal Twitter account.

That post read, "Let's be clear: Donald Trump does not have the authority to take us into war with Iran without Congressional approval. A president should never take this nation to war without the informed consent of the American people."

This was a genuine post that was shared on Biden's personal account on Jan. 6, 2020.

At the time, Biden was campaigning to become the Democratic nominee for the 2020 presidential election.

Biden's Strikes on Iranian-Backed Houthi Rebels

The context underlying Greene's sharing four-plus-year-old post in January 2024 was breaking news out of the Middle East. On Jan. 11, U.S. and U.K. forces launched retaliatory strikes on more than a dozen sites in Yemen against Iranian-backed Houthi rebels, who had previously been warned by the U.S. and 12 allies to cease their drone and missile attacks against commercial vessels in the Red Sea.

The Houthi attacks were the rebels' way of avenging Israel’s offensive in Gaza against Hamas, The Associated Press reported.

On Jan. 12, during a stop at a coffee shop in Emmaus, Pennsylvania, Biden was asked by a reporter, "Are we in a de facto proxy war with Iran?"

"No," Biden answered, moments later saying that "Iran does not want a war with us."

Gen. Soleimani's Death and Troop Deployments

As for why Biden posted in early January 2020 about then-U.S. President Donald Trump needing congressional approval to go to war with Iran, that matter concerned the aftermath of the death of Gen. Qassem Soleimani, the leader of Iran’s Islamic Revolutionary Guards Corps.

Soleimani was killed in a drone strike at Baghdad International Airport on Jan. 3, 2020. The strike was authorized by Trump. At the time, U.S. Secretary of State Mike Pompeo told CNN that the reason for the strike was concerns over an "imminent attack" that could potentially have led to American lives lost in the region.

On the same day that Biden posted his tweet, The New York Times reported that, in the aftermath of Soleimani's death, the Pentagon had directed about 4,500 additional troops to the Iraq and Syria on top of the roughly 50,000 who were already there. That escalation was likely what led to Biden's tweet.

In practical terms, the question of what military actions a president is allowed to take under the U.S. Constitution has remained a legal gray area, despite the passage of the War Powers Act in 1973. We explored that question in a previous article: Can US Presidents Launch Airstrikes Without Congressional Approval?
