Story highlights Trump made his first foreign stop as President to Saudi Arabia

Some politicians said he should have addressed human rights

Washington (CNN) Politicians from both parties knocked President Donald Trump on Sunday for not making a forceful case for human rights during a speech in Saudi Arabia.

In his speech, Trump said he was not there to "lecture" Muslim countries, but he did call for nations to promote "the aspirations and dreams of all citizens who seek a better life -- including women, children and followers of all faiths."
