Democrat Illinois State Sen. Terry Link pleaded guilty today to a federal tax charge and admitted willfully underreporting his income for several years just days after he resigned.

Link, a Democrat, admitted in a plea agreement that he willfully underreported his income on his tax returns for the calendar years 2012 through 2016.

The conduct caused total losses to the IRS of at least $71,133, and to the Illinois Department of Revenue of at least $11,527, the plea agreement states.

For the calendar year 2016, Link admitted that he underreported approximately $93,859, approximately $73,159 of which was money from a campaign fund – Friends of Terry Link – that Link spent on personal expenses, the plea agreement states.

Link, 73, pleaded guilty to one count of filing a false tax return, which is punishable by up to three years in federal prison. He agreed to pay restitution of $71,133 to the IRS, and $11,527 to the Illinois Department of Revenue.

U.S. District Judge Robert M. Dow, Jr., did not immediately set a sentencing date. A status hearing was set for March 30, 2021, at 9:00 a.m.

Court documents from a year ago suggested that Link, 73, cooperated with the feds against another Democrat state lawmaker, then-state Rep. Luis Arroyo, in anticipation of the false tax return charge, hoping it would lead to a reduced sentence, according to a Chicago Sun-Times report.

Link publicly denied last fall that he was the unnamed senator in the court documents indicting Arroyo. The Vernon Hills Democrat denied it multiple times.

Prosecutors first charged Arroyo with bribery in a criminal complaint in October, revealing the unnamed state senator had been cooperating with them off and on since 2016. The feds say Arroyo tried to bribe the senator to introduce legislation that would legalize sweepstakes machines.
