=After a day of peaceful protests in Los Angeles, tensions mounted between protesters and Marines outside the federal building in downtown LA.
Some protesters chanted "shame" and booed the Marines, who were accompanied by federal law enforcement.
In Texas, the state capitol and capitol grounds were evacuated Saturday afternoon because of a "credible threat against state lawmakers planning to attend" the No Kings protest there, according to a Texas Department of Public Safety spokesperson.
An armed man who allegedly made threats against Republican officials has been detained while he was en route to Austin, a law enforcement official briefed on the situation told ABC News.
The Capitol grounds have since been reopened.
Thousands of "No Kings Day" protests were expected across the U.S. on Saturday to protest the Trump administration and to counterprogram the military parade in Washington, D.C.
Fliers reading "No Kings" were found in the car of the suspected gunman who is wanted for killing a Minnesota state lawmaker and wounding a second state lawmaker near Minneapolis early Saturday.
Protestors wearing shirts reading "make out not war" climbed on top of a military vehicle ahead of the Army parade.
In addition to the flood watch in place until 11 p.m., the National Weather Service says that gusting winds could roll through the Washington area.
The White House has said that the parade goes on rain or shine, but lightning could bring things to a halt.
