AUSTIN-- Vice President Joe Biden will be in Austin on Wednesday.

Biden is coming to town to visit the headquarters of the NationalDomestic Violence Hotline to celebrate the center's three millionth call and congratulate the advocates who work there.

Biden last visited the Austin-based National Domestic Violence Hotline in 2009. He also came while a U.S. senator from Delaware three years before that.

Wednesday Biden will help launch a new online chat service where victims can communicate with call takers through the computer or smartphone.

Hotline President Katie Ray-Jones said more than 100 staff members handle about 22,000 calls a month but that capacity issues meant they were still unable to get to almost 52,000 calls in 2012 alone.

Meanwhile, the center has seen traffic on its website increase 30 percent over the past 12 months.

Back in 1991, Biden co-authored the Violence Against Women Act that helped found the center.
