Not "use"; more like "go to (or into, or on to)". For example, "The protesters took to the streets to spread their message"; or "The villagers took to the hills to avoid the invading army".
So, in your case, the lawmakers went on television/radio.
I suspect that "take to", in this sense, may be a shortening of "take oneself to" — though I can't find any firm proof of that.
The word go has so many senses.
Which sense matches the use of "went"?
