Tax returns -- DC Circuit Court of Appeals
In a 2-1 ruling, the US Court of Appeals for the District of Columbia Circuit rejected Trump's attempt to stop his accounting firm, Mazars USA, from turning over eight years of financial records to House Democrats.
It's a major loss in the President's efforts to refuse to cooperate with the impeachment probe. Trump and other Republicans argue the full House must vote to authorize the inquiry, but the court disagreed, writing that it has "no authority" to require the House to take a full vote in support of a subpoena to investigate the President, citing the Constitution.
The next stop could be the Supreme Court.

Border wall -- Western District of Texas
Judge David Briones said Trump's national emergency declaration to build a border wall is unlawful, and appears poised to block the use of those funds.
El Paso County, Texas, and the Border Network for Human Rights say Trump overstepped his authority when he issued the declaration to gain access to additional funds for his border wall, despite receiving $1.375 billion from Congress.
The ruling is limited, however, in that it applies only to the military construction funds that have been diverted for wall construction, not to other sources such as counterdrug funding and Treasury Forfeiture Funds.
