Can the president attack another country without Congress?

Indiana Reacts to US Airstrikes in Syria

US President Donald Trump has meanwhile written to both chambers of Congress justifying his decision to launch the retaliation strikes.

Trump had made it clear at a news conference in Mar-a-Lago Thursday that the US would retaliate against the gruesome chemical attack on civilians in Syria.

"The use of chemical weapons on innocent people can not be ignored, and I am encouraged to see that after years of indecisiveness and inaction from the previous administration, that President Trump has chose to stand up against Bashar al-Assad's regime".

Three days after the September 11 terrorist attacks, Congress voted to give former President George W. Bush broad executive authority to wage war overseas.

But Kaine argued it wasn't a case of self-defense, in which the President is authorized to use military force without the approval of Congress.

"Let's be very very clear about this", Kaine said.

Rubio is a Florida Republican and onetime rival of President Donald Trump.

"Times change. In 13, Speaker asks Obama how: "justification comports with exclusive authority of Cong authorization" tweeted Ben Rhodes, a deputy national security adviser under Obama.

Yet in the present day, almost every Texas Republican in Congress favors Trump's actions on Syria. "What will we get for bombing Syria besides more debt and a possible long term conflict? There has to be congressional approval".

"Assad choked out the lives of helpless men, women and children", Trump said at a Mar-a-Lago presser Thursday.

The airstrike killed six people according to various reports.

But Ryan, by stopping short of advocating for a new resolution authorizing the use of military force, is certain also to disappoint a number of members who say Congress's constitutional power is being trampled by continual military activity in Syria and other terrorist hotbeds. Marco Rubio - that "from a moral standpoint ... it was the right thing to do", he said Trump was wrong to not obtain the go-ahead from Congress.

He continued, "I was a Senate candidate in 2011 when President Obama joined military action against Libya". That's rich, since President Obama never did have a strategy on Syria or the defeat of the Islamic State.

President Trump on Saturday tried to explain why a US attack against a Syrian air base didn't destroy the runway.

"We had been reckoning with this for five years and there aren't easy answers".

"All you're anxious about is what is ethically right", said a third person, "You know, it's just talking about war crimes".

It's also rich that this resolute military strike on a Russian client comes in the middle of Democrats' quixotic quest to prove Mr. Trump is somehow a stooge of the Kremlin.

"I'm the Democratic lead on the committee over the Middle East; I was not consulted", said Kaine, who chairs the Senate Foreign Relations Subcommittee on Near Eastern and South and Central Asian Affairs.
