<p>GRAND RAPIDS, Mich. — Prosecutors added charges Wednesday against three of six people accused of plotting to kidnap Michigan Gov. Gretchen Whitmer.</p>
<p>Adam Fox, Barry Croft Jr. and Daniel Harris conspired to use a weapon of mass destruction, namely a plan to blow up a bridge near Whitmer’s second home in northern Michigan to hinder police, according to an expanded indictment filed in federal court in Grand Rapids.</p>
<p>The role of the bridge in the alleged plot was disclosed by authorities months ago. </p>
<p>Croft and Harris also were charged with possession of an unregistered destructive device. Harris also faces a new charge of possession of an unregistered short-barreled rifle.</p>
<p>The three men, along with Kaleb Franks and Brandon Caserta, were arrested in October and indicted on a kidnapping conspiracy charge. They have pleaded not guilty. A sixth man, Ty Garbin, <a href="https://apnews.com/article/ty-garbin-plead-guilty-kidnap-whitmer-e75bd5bd6afef044b20efde2559ea855">pleaded guilty</a> in January.</p>
<p>The FBI said it broke up a plot to kidnap Whitmer, a Democrat, by anti-government extremists upset over coronavirus restrictions she had imposed in Michigan. A separate group has been charged in state court with aiding them.</p>
