CommandText property has not been initialized

Hejsa
Jeg får fejlen "CommandText property has not been initialized", når jeg prøver at hente data fra min SQL server.

Koden:
        public List<Branch> BranchSelectByUser(int id)
        {

            List<Branch> colBranchUsers = new List<Branch>();

            SqlConnection con = new SqlConnection(_connectionString);

            SqlCommand cmd = new SqlCommand();
            cmd.Connection = con;
            using (con)
            {
                con.Open();
                SqlDataReader reader = cmd.ExecuteReader();
                cmd.CommandText = "SELECT b.description, From branch_user bu, Branchs b, users u where b.id = bu.id and bu.userid = u.id and u.id =1";

                while (reader.Read())
                {
                    colBranchUsers.Add(new Branch((int)reader["id"],
                        (string)reader["description"],
                        (string)reader["contact"]));
                }
            }
            con.Close();
            return colBranchUsers;
         

        }
