FORTUNE -- In subcommittee hearings Tuesday, Senators Carl Levin and John McCain were careful to balance praise for Apple's (AAPL) achievements with outrage over its "convoluted and pernicious" (McCain's words) tax avoidance strategies.
Sen. Rand Paul showed no such balance. He lit into his own committee's leadership for "dragging" one of America's great success stories into what he called a "show trial."

Sen. Levin, with comparable heat, told Sen. Paul he could apologize to Apple if he wanted, but that was not the purpose of the subcommittee hearings.
Paul, not content to let it lie there, began tweeting:
