The assassination of a Democratic Minnesota state lawmaker and her husband and the shooting of another lawmaker and his wife at their homes are just the latest addition to a long and unsettling roll call of political violence in the United States.

The recent shootings of lawmakers in Minnesota are part of a disturbing trend toward politically linked violence, ABC News analysts say.

Threats and violent acts have become part of the political landscape, still shocking but somehow not so surprising.

Authorities are on the second day of the hunt for a man suspected of killing Minnesota State Rep. Melissa Hortman and her husband at their house. The suspect also is believed to have shot State Sen. John Hoffman and his wife in their home.

A manhunt is underway for the gunman who was impersonating a police officer and had a list of possible targets, officials said.

Ramsey County Sheriff's Office via FacebookMinnesota Governor Tim Walz said Sunday that police arrested a suspected gunman accused of killing a Democratic state lawmaker and her husband, while posing as a police officer.

Political leaders from both sides of the aisle are condemning political violence following the shootings of two Minnesota lawmakers. House Minority Leader Hakeem Jeffries joins The Weekend to discuss this plus the massive turnouts for “No Kings” protests in the face of Trump’s military parade.

While Washington hosted a military parade, large crowds gathered across the country Saturday to peacefully protest President Donald Trump’s policies. The threat of violence – and news of a political assassination in Minnesota – added to tensions.
