Republicans are in general doing the same as Democrats did during the last several years.  For those that don't care for Trump and the republicans, there's at least partial "blame" to Obama as under his leadership Republicans won many seats including the big one, President.  Put another way, if Obama was able to better unite our country, it's very likely Democrats would have continued to hold majority.  As for environmental laws and regulations which I'm very familiar with, there are many that have been put in place that does not add real value to preserving the environment.  Most add administrative burden to the regulated community and justifies regulators such as the EPA and DOH to expand their staffing; most of us know the drill, new laws so we need more people.
