The lower federal courts repeatedly have had their orders and injunctions against Trump administration programs halted by the Supreme Court. In the travel cases, multiple stays were issued and when the case finally reached the Supreme Court on the merits, Trump won.
This is not a matter of pro-Trump bias, but of out-of-control lower courts, particularly at the District Court level, where judges have overstepped their bounds to substitute judicial preferences for those of the executive branch in which the constitution vests matters related to entry into the country, among other things.
