The Tax March is an international movement of people coming together to demand transparency and financial disclosure by President Trump. Every march and marcher has their own specific reasons and set of principles which have led them to believe this transparency is necessary.
Detroit, Michigan March Principles
The ONLY reason to join the TrumpTaxesMarch in Detroit is ---- You Care!
You care about preserving the integrity of the Office of The President of the US. Trump promised to release his taxes.
You care that citizens' rights, protected by the US constitution, are upheld. The Bill of Rights was added to the Constitution in the form of amendments. The chief purpose of the amendments was to protect the rights of individuals from the government's interference. They guarantee rights such as religious freedom and freedom of the press.
You care that an average citizen should not be transformed into a king after being elected as US President -- not held to the same standards against outright lying, propagating fake news, and under FBI investigation.
