wp_oembed_get doesn't work with tweets anymore

Hi,

Do you have any idea why this is working:
echo wp_oembed_get(‘https://www.youtube.com/watch?v=HG7I4oniOyA’);

And, more importantly, why is this NOT working?

echo wp_oembed_get(‘https://twitter.com/PatriceStephens/status/423411521277153280’);

The first outputs a YouTube video, the second doesn’t return anything. The second one was working a few months ago. I use this to get a tweet URL from a post_meta to show in the sidebar and just narrowed it down to Twitter. Maybe something changed in either Twitter or WordPress?

Best,
