House Speaker T.W. Shannon, R-Lawton, said Thursday he is asking Reps. Mark McCullough, R-Sapulpa, and Jason Nelson, R-Oklahoma City, to form a bipartisan group to examine the state's home visitation programs. McCullough and other House members have voiced concerns over the decline in families being serviced and the effectiveness of the Children's First Home Visitation Program over the past decade. Workers under the program visit the homes of at-risk families to evaluate living conditions of children. Members will look at each state visitation program over the next year and talk with affected constituents and local and national experts.
