Joe Biden will also speak about gun violence during tonight’s speech, according to USAToday. On the presidential campaign trail, Biden pledged to reinstate the assault weapons ban and create a voluntary gun buyback program.

A White House official told the newspaper that Biden will talk about gun violence as an epidemic, which he has done in the past, and urge Congress to reinstate a ban on assault weapons and high capacity magazines.

The president’s plea appears to echo a similar one made by Obama at the State of the Union in 2013, two months after Sandy Hook, in which he told Congress victims of gun violence — many of whom were seated in the room — “deserve a vote.” Biden presided over the Senate chamber when a gun safety package failed to pass two months later.

Despite the uphill battle, Democrats are heeding the president’s call. Last week Sen. Richard Blumenthal, D-Conn., and Rep. Adam Schiff, D-Calif., reintroduced a bill to remove protections for manufacturers and sellers from consumer negligence lawsuits and allow victims of gun violence to pursue legal recourse. Sen. Chris Murphy, D-Conn., a key Democrat leading gun control efforts, told CNN’s Anderson Cooper last week that he’s made calls to almost half the Republican caucus “asking them to keep an open mind.”

The Guardian’s voting rights reporter, Sam Levine, has an alarming story this morning on Republican efforts to make it harder to vote in Joe Biden’s first 100 days in office:

Even as attacks on voting rights have escalated in recent years, the Republican effort since January marks a new, more dangerous phase for American democracy, experts say.
