How to display posts from 2 categories in the same Custom Taxonomy

I figured out how to display posts from multiple custom taxonomies and how to pull posts from a specific category in a taxonomy, but I can’t for the life of me figure out how to display posts from 2 categories within a single taxonomy.

The code below shows posts from the News post type and from the General News category in the News Type taxonomy. How can I modify this to add posts from the Press Release category in the same taxonomy?

<?php
$args=array(
  'post_type' => 'news',
  'news-type' => 'general-news',
  'post_status' => 'publish',
  'posts_per_page' => -1,
  'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
  while ($my_query->have_posts()) : $my_query->the_post(); ?>
  <p><?php the_title(); ?></p>
  <p><?php the_content(); ?></p>
  <?php endwhile; } wp_reset_query();?>
