A libertarian talk show host led a convoy of volunteers with shovels and pickaxes to Waco on Sunday to begin rebuilding the Branch Davidians' compound church.
A fire during a government raid April 19, 1993 after a 51-day standoff leveled the compound, killing leader David Koresh and about 80 followers.
Austin talk show host Alex Jones, 25, said Sunday he wants to rebuild the church as a memorial and to increase publicity about the FBI's possible role in the fire.
Jones said he chose now to build a memorial and church because of a recent admission by the FBI that agents had fired potentially incendiary tear gas canisters at the compound the day it burned, despite years of statements to the contrary. Attorney General Janet Reno earlier this month appointed a special counsel to investigate.
The rebuilding project is expected to take two to three months.
