US President Donald Trump said on Friday he would consider bombing Iran again if Tehran was enriching uranium to a level that concerned the United States, adding that he supports inspections of Iran's bombed nuclear sites.

"Sure, without question, absolutely," Trump said when asked about the possibility of new bombing of Iranian nuclear sites if deemed necessary at some point.

At a White House press conference, Trump said he plans to respond soon to comments from Iran's Supreme Leader Ali Khamenei, who said Iran "slapped America in the face" by launching an attack against a major US base in Qatar following last weekend's US bombing raid.

The Republican-led US Senate rejected a Democratic-led bid on Friday to block President Donald Trump from using further military force against Iran, hours after the president said he would consider more bombing.

The Senate vote was 53 to 47 against a war powers resolution that would have required congressional approval for more hostilities against Iran. The vote was along party lines, except Pennsylvania Democrat John Fetterman voted no, with Republicans, and Kentucky Republican Rand Paul voted yes, with Democrats.

Senator Tim Kaine, chief sponsor of the resolution, has tried for years to wrest back Congress' authority to declare war from both Republican and Democratic presidents.

Kaine said his latest effort underscored that the US Constitution gives Congress, not the president, the sole power to declare war and requires that any hostility with Iran be explicitly authorized by a declaration of war or specific authorization for the use of military force.

"If you think the president should have to come to Congress, whether you are for or against a war in Iran, you'll support Senate Joint Resolution 59, you'll support the Constitution that has stood the test of time," Kaine said in a speech before the vote.

Lawmakers have been pushing for more information about weekend US strikes on Iran, and the fate of Iran's stockpiles of highly enriched uranium.

Earlier on Friday, Trump sharply criticized Iran's Supreme Leader, Ali Khamenei, dropped plans to lift sanctions on Iran, and said he would consider bombing Iran again if Tehran is enriching uranium to worrisome levels.

He was reacting to Khamenei's first remarks after a 12-day conflict with Israel that ended when the United States launched bombing raids against Iranian nuclear sites.

Trump wishes for Iran's nuclear sites to be inspected

Trump also said he would like inspectors from the International Atomic Energy Agency or another respected group to be able to inspect Iran's nuclear sites after they were bombed last weekend.

Trump said he believes the sites were "obliterated." He has rejected any suggestion that the damage to the sites was not as profound as he has said.

Trump also said he does not believe Iran wants to seek a nuclear weapon after the US and Israeli bombing raids.

He said Iran still wants to meet about the path forward. The White House had said on Thursday that no meeting between the US and an Iranian delegation has been scheduled thus far.
