Many rioters who stormed the Capitol received long prison sentences. Sidney Powell, an architect of the effort to subvert the election, negotiated a misdemeanor plea deal and cooperation agreement.

When Sidney Powell, a top ally of Donald Trump, pleaded guilty Thursday to crimes associated with the 2020 election, lawyers for many Jan. 6 defendants were stunned by her relatively meager sentence: six years of probation and a modest fine.

For years, those lawyers — and some judges — have lamented that the thousands who breached the Capitol were used as pawns and dupes by Trump, Powell and their associates in a bid to subvert the election. So Powell’s plea was the first taste of accountability for Trump’s inner circle. Yet her punishment, Jan. 6 defense lawyers noted, paled in comparison to even some of the low-level offenders who entered the Capitol that day and now face consequences that may dog them for life.
