Trump fires back against ads

Some pretty outrageous things have come out of Donald Trump's own month, but he doesn't like it when people say things about him.

He's threatening a conservative group with a multi-million dollar lawsuit unless they stop running ads saying he is too liberal to be president.

Trump fired off a letter to the group this week, but they have yet to respond or pull the ads.

Trump continues to lead the GOP field for president with support nearing 25 percent, according to the latest polls.
