Kamala Harris laid out a gun control plan Wednesday that focuses on domestic terrorism, proposing action to add online gun sellers to background check requirements and expand the mission of the National Counterterrorism Center to include domestic terrorism.

If elected, Harris said she would take executive action to require major online gun sales platforms to perform background checks, ensure domestic terrorism is included in the counterterrorism center's mission and commit $2 billion to investigate and prosecute domestic terrorists. Under federal law, unlicensed dealers may be legally allowed to sell firearms without conducting a background check, and those sales can occur at gun shows or online.

The Democratic presidential candidate also said she would give law enforcement new tools to fight domestic terrorism by petitioning federal courts to temporarily seize guns from terrorism suspects or individuals who may commit a hate crime.
