Input: Strict gun control advocate  Sen. Chris Murphy  said Sunday  he ’s “willing to move forward” with Republicans to ban the bump-stock devices that were used in the nation’s worst mass shooting.
“The NRA at least in the time I have been in Congress has never been willing to change U.S. gun laws ”  Murphy  said. “I think they see that they were likely going to lose this fight in Congress  and so now they’re trying to get it done through administrative action. But this is the first time that the gun lobby has shown willingness to come to the table.”
 Murphy  said  however  Congress should mandate background checks for all gun purchases.
"That would be the clear next step "  he  said. "That should be our North Star."
Also in the interview   Murphy  said the Democratic Party should give back donations received from the Hollywood mogul Harvey Weinstein  who’s embroiled in a sex harassment scandal.
"I think that probably makes sense "  he  said. "I mean this is a pretty bad guy  who did some really awful things."
"I don't require a background check to contribute to my campaign "  he  added. "And so there are probably lots of people with unsavory backgrounds and pasts who have given to both Democrats and Republicans."
