Washington-The Justice Against Sponsors of Terrorism Act (JASTA) has now become a source of headache for U.S. lawmakers as some of them tried to justify their decision to pass the bill by blaming the White House for being unclear in explaining the law’s repercussions.

However, the White House replied to the Congress decision saying some Congressmen had behaved like schoolchildren when dealing with the bill.

Last week, the Congress overrode U.S. President Barack Obama’s veto of JASTA, a bill that allows U.S. citizens to sue Saudi Arabia over the September 11 terrorist attacks.

ABC television had quoted White House Spokesman Josh Earnest as comparing the U.S. Congress to elementary schoolchildren for overriding Obama’s veto of JASTA.

“It’s hard to take at face value the suggestion that they were unaware of the consequences of their vote. And, even if they were, ignorance is not an excuse, particularly when it comes to our national security and the safety and security of our diplomats and our service members,” he said.

The spokesman replied to Congressmen’s accusations that the bill was not clearly explained by the White House by saying: “Last April, Obama had publicly discussed the JASTA’s potential negative impact.”

The spokesperson added: “I think what we’ve seen in the U.S. Congress is a pretty classic case of rapid onset buyer’s remorse.”

Meanwhile, several officials from the Republican Party said they would reconsider the bill.

Senate Majority Leader Mitch McConnell said last week that JASTA may have “unintended ramifications,” despite Congress’s overwhelming vote to pass it.

McConnell added it seems there are some unintended ramifications, “and I do think it’s worth further discussing. But it was certainly not something that was going to be fixed this week.”

Last week, Obama blamed the Congress for its decision to override his veto saying it was “a dangerous precedent.”

Obama told CNN that members of Congress made a “political vote” by voting overwhelmingly to override his veto.
