Hate to break it to the Little Trunpsters but there is a law that allows certain representatives to look at Trump's tax returns. They just can't release those records to the public.

Congressional Authority to Obtain
And Release Tax Returns
by George K. Yin
President Trump’s continuing refusal to release
his tax returns despite the contrary common prac-
tice of presidents over the last 40 years has spurred
interest in finding alternative ways to obtain the
information.

This article describes the authority of
Congress, under section 6103(f)(1) and (4)(A), to
obtain, inspect, and disclose the confidential tax
information of any taxpayer, including the presi-
dent, without the taxpayer’s consent. The authority
may be exercised by any one of three tax commit-
tees: the House Ways and Means Committee, the
Senate Finance Committee, and the Joint Commit-
tee on Taxation

Under specific circumstances, other congressional commit-
tees, as well as the chief of staff of the JCT, also have the right to
obtain protected tax information, but they have no ability to
disclose it to the public without the taxpayer’s consent. Section
6103(f)(2), (3), and (4)(B). Also, many other persons may obtain
tax information for tax administration and other purposes, but
they generally may not disclose it further.
See
section 6103(a)(2)
and (3). This article is limited to the right of the tax committees
to obtain and disclose the information
