Senator Tom Cotton says President Donald Trump could have US forces impose a 'world of hurt' on Mexican cartels after the Mormon massacre that killed nine.
The Republican told Fox News on Wednesday America may be forced 'to take matters into our own hands' if the Mexican government 'cannot protect American citizens' in the country.
His comments follow the grisly slaughter of three mothers and six children in the northern state of Sonora on Monday.
Cotton, a member of the Senate Armed Services Committee, doubled down on comments he made Tuesday where he suggested 'the only thing that can counteract bullets is more and bigger bullets'.

Rhonita Miller and four of her children - her six-month-old twins, Titus and Tiana, her 10-year-old daughter Krystal and 12-year-old son Howard - were all killed. Another two mothers, Dawna Langford and Christina Langford Johnson, as well as Dawna's sons, Trevor, 11, and Rogan, 3, were also all killed in the massacre on Monday in the northern state of Sonora
The morning after the killings, Trump, left, on Twitter urged Lopez Obrador to call him so the two could jointly pursue those responsible for the killings in Sonora. When informed about Trump's tweets, Lopez Obrador, right, told a news briefing he believed Mexico could handle the case without any intervention by a 'foreign government'
The Arkansas senator, a close ally of Trump's on Capitol Hill, told Neil Cavuto on Tuesday: 'It's plain that the Mexican government can't handle this.
'President Lopez Obrador came into office almost a year ago saying that his strategy for dealing with the cartels was going to be more hugs, not bullets.
'That may work in a children's fairy tale, but in the real world when three American women and six American children were gunned down and burned alive the only thing that can counteract bullets is more and bigger bullets.
'If the Mexican government cannot protect American citizens in Mexico, then the United States may have to take matters into our own hands.'
He added: 'We can certainly defend American citizens inside of Mexico if Mexico is not willing or able to do so.'
Cotton followed up Wednesday by reiterating those points and adding: 'Our special operations forces were able to take down [ISIS leader Abu Bakr] al-Baghdadi in Syria a couple of weeks ago, they did it to Usama Bin Laden in Pakistan eight years ago.
'I have every confidence that if the president directed them to do so, they could impose a world of hurt on these cartels a few dozen miles away from the American border.'
