Q: WASHINGTON — They called themselves "crusaders" for a reason.
The three Kansas militiamen planned to blow up an apartment complex housing Somali refugees during the 2016 presidential election, unleashing what one of them called "Crusades 2.0."
But their plan was foiled after their arrest just weeks before the election, highlighting the changing enemy list of a movement founded on the back of anti-government activism a generation ago.
And with the election of a president whose policies many militia members support, the urge to confront the government appears to have lost some of its urgency. Instead of railing at the government, they have in recent years turned their venom against new-found foes: Muslims, immigrants, the Antifa.
"Some of the militia groups have been refocusing their attention on secondary enemies for the movement," said Mark Pitcavage, who researches extremism at the Anti-Defamation League civil rights group.
Often lumped together with other right-wing groups, the anti-government movement comes in different forms.
There are the "preppers," so called because they stockpile water, food and other essentials in preparation for civil unrest.
There are the "survivalists," people who learn skills to "live off the land" in case of a disaster.
There are "sovereign citizens" such as the suspect in the recent shooting at a Waffle House in Tennessee who are opposed to paying taxes and believe they should decide which laws to follow.
And then there are the militiamen who conduct regular military-style training to resist a government they see as engaged in a global plot to take away their guns and constitutional rights.
The modern militia movement dates back to a series of events in the early 1990s, according to the Southern Poverty Law Center.
Among them: the 1992 election of Democratic President Bill Clinton and an FBI attack the following year on the Branch Davidian compound in Waco, Texas, an event seen as "evidence of an out of control government willing to attack citizens."
Under Clinton, the number of anti-government groups soared but it fell during President George W. Bush's two terms before peaking at 1,360 under President Barack Obama. Question: Which anti government group does not believe in paying taxes and that they should be able to decide which laws to follow?
A: 
sovereign citizens
