President Donald Trump vetoed legislation that limited a president's ability to wage war against Iran without Congressional approval.
On Wednesday, Trump said he vetoed the resolution of Iran's war powers because it was "an insult" to the presidency.
In a statement, he argued that the non-binding legislation "intended to instruct me to end the use of the United States Armed Forces in hostilities against Iran".
Congress approved the resolution of Iran's war powers after the assassination of Iranian general Qassem Soleimani by the United States, amid widespread concerns about tensions between the US and Iran.
At that time, the resolution – presented to Congress by Democratic Senator Tim Kaine – showed bipartisan support for President Trump's reigning war powers.
"This was a very offensive resolution, presented by Democrats as part of a strategy to win an election on November 3, dividing the Republican Party," Trump said in the White House statement on Wednesday. "The few Republicans who voted in favor played straight into your hands."
In another White House memo, CNN reported, the president said that "this indefinite ban is unnecessary and dangerous".
“The resolution implies that the president's constitutional authority to use military force is limited to the defense of the United States and its forces against imminent attacks. This is incorrect, ”said Trump on Wednesday.
Trump continued: "We live in a hostile world of evolving threats, and the Constitution recognizes that the president must be able to anticipate our opponents' next moves and take quick and decisive action in response. That's what I did!"
Congress is not expected to override the president's veto during a vote on Thursday, as Republicans hold a 53-47 majority in the US Senate.
Kaine on Wednesday asked senators to vote with him to override the veto, saying on Twitter: "I ask my colleagues to join me in the vote to override their veto – Congress must vote before sending our troops into danger. ".
The resolution was passed by the Chamber of Deputies in March and the Senate in April, with the support of a small number of Republicans.
