President Trump said in a statement that he will "not rest" until US schools are made safe, adding "tremendous strides" have already been made.
"Today, as we hold in our hearts each of those lost a year ago in Parkland, let us declare together, as Americans, that we will not rest until our schools are secure and our communities are safe," Trump said.
Calling school safety "a top priority," Trump listed measures including a ban on bump stocks -- a modification allowing store-bought semi-automatic weapons to fire similarly to a full automatic weapon, delivering an uninterrupted torrent of bullets.
Trump said to care for mental health and school security was also much improved since last year.
However, efforts to curb the steady flood of US gun violence are tightly constrained by pressure from Trump's Republican Party and the gun ownership rights' lobby, which see even modest restrictions on access to firearms as violating the constitution.
The city of Parkland, Florida came to a standstill today to remember the victims of a school shooting that took the lives of 17 people on Valentine's Day one year ago, igniting a student crusade against gun violence.
Students and families observed a moment of silence and community service activities were scheduled for local schools, with the city hosting an evening vigil at a park.
Seventeen students were killed on February 14 last year after a former student with an assault rifle opened fire inside his school in Parkland, Florida.
