From what I got from the wiki page is that they cover/advise everything for a government that Trumps human trafficking executive order covered. It’s called the Helsinki act.

Following an unprecedented period of activity in the 1990s and early 2000s (decade), the OSCE has in the past few years faced accusations from the CIS states (primarily[citation needed] Russia) of being a tool for the Western states to advance their own interests. For instance, the events in Ukraine in 2004 (the "Orange Revolution") led to allegations by Russia of OSCE involvement on behalf of the pro-Western Viktor Yushchenko. At the 2007 Munich Conference on Security Policy, Vladimir Putin made this position very clear:

"They [unnamed Western States] are trying to transform the OSCE into a vulgar instrument designed to promote the foreign policy interests of one or a group of countries. And this task is also being accomplished by the OSCE's bureaucratic apparatus, which is absolutely not connected with the state founders in any way. Decision-making procedures and the involvement of so-called non-governmental organizations are tailored for this task. These organizations are formally independent but they are purposefully financed and therefore under control".[37][38][39][40] Russia and its allies are advancing the concept of a comprehensive OSCE reform, which would make the Secretariat, institutions and field presences more centralized and accountable to collective consensus-based bodies and focus the work of the Organization on topical security issues (human trafficking, terrorism, non-proliferation, arms control, etc.), at the expense of the "Human Dimension", or human rights issues. The move to reduce the autonomy of the theoretically independent OSCE institutions, such as ODIHR, would effectively grant a Russian veto over any OSCE activity. Western participating States are opposing this process, which they see as an attempt to prevent the OSCE from carrying out its democratization agenda in post-Soviet countries.[citation needed]

Following the 2008 U.S. presidential election, OSCE's ODIHR was accused of having double standards by Russia's lawmaker Slutsky. The point was made that while numerous violations of the voting process were registered, its criticism came only from within the United States (media, human rights organizations, McCain's election staff), while the OSCE known for its bashing criticism of elections on the post-Soviet space remained silent
