By publishing a statement, Biden said that preventing armed violence in the US requires more serious action.
A day before, a number of members of the US parliament proposed a plan based on which people under the age of 21 are not allowed to use weapons.
This is despite the fact that from January 1 to 23 of this year, 70 people were killed in armed attacks in the US or committed suicide using weapons.
In the latest case on Tuesday, a gunman killed three people with a bullet in Washington State.
