He cannot be just the 'Chief comforter.' Peter Ambler of the Giffords Association, which advocates for stronger regulation of US President Joe Biden, stated that he must use all the power of his office to win the legislative battle.

The 79-year old Democrat has so far resisted the temptation to join the fight for stricter gun regulations. This is both a personal choice and a strategic calculation.

This is the president's role as "chief comforter". He wants to believe that Americans can, despite their differences, mourn the deaths of 19 schoolchildren (Texas) and 2 teachers in the shooting at Uvalde (Texas). He will be there with his wife Jill Biden.

Joe Biden is currently a proponent of the register of emotion, questioning and the register of emotions. "When for love of God will we face the gun lobby?" He exclaimed Tuesday that it was also political calculation.

Former senator attached to parliamentary power wants Congress to pass a bill which would broaden the examination of the mental and judicial backgroundss arms buyers while banning assault rifles as well as the large-scale purchase of ammunition.

The White House believes that Joe Biden's strong involvement at a time of low poll numbers would disrupt an already complex legislative process more than anything.

Because of qualified majority rules, the Democrats who support the bill must convince a few elected Republicans.

Joe Biden has not yet openly criticized the Republican opposition, which is hostile to any reform. Some of their members are running for November's legislative elections, focusing on their attachment to firearms.

A federal law, according to the American executive, would have a greater impact than presidential decrees which are not binding on all American States and can only be regulated at the margins.

Many groups advocating regulation of firearms agree with the convictions of President Trump that he should be more involved. Director of Guns Down America, Igor Volsky believes the president should create a White House agency that is specifically focused on firearms. He could travel across the country to meet with affected communities and receive activists, as well as exert pressure on the parliamentarians.

The fear is that the United States could slip back into the same scenario as after a mass shooting: A wave of emotion that subsides, before turning into real pressure and leading to important reforms.
