Liberal MSNBC anchor Rachel Maddow will host an April 19 special on Timothy McVeigh's 1995 act of terrorism and how it "puts into perspective the threat posed by anti-government extremism."

In an ad for the program, Maddow lectured, "It doesn't have to lead to violence, but it can and it has. We ignore this, our own very recent history of anti-government violence and the dangers of domestic terrorism, at our peril."

In a previous commercial for the special, an announcer questioned, "15 years later, can McVeigh's words help us understand today's anti-government extremists?" Will the left-wing host attempt to connect tea partiers and conservative activists to violence?

It wouldn't be the first time. On March 22, Keith Olbermann, Maddow's colleague on the cable channel, attacked such protesters for their "incitement to violence."

On April 15, 2009, MSNBC used the Republican elephant logo in a segment on violence and the "radical right."

Maddow's special airs at 9pm on April 19.

A transcript of the MSNBC ad, which aired on April 12, follows:

VOICE OF TIMOTHY MCVEIGH Text onscreen: Oklahoma City, April 19, 1995]: I feel no shame for it.

ANNOUNCER: An MSNBC special presentation with Rachel Maddow.

RACHEL MADDOW: The McVeigh Tapes puts into perspective the threat posed by anti-government extremism. It doesn't have to lead to violence, but it can and it has. We ignore this, our own very recent history of anti-government violence and the dangers of domestic terrorism, at our peril.
