(CNN) As federal employees brace themselves for their second missed paycheck should the government not reopen in time to make payroll by Tuesday, some members of Congress have decided to join them in a show of solidarity and refuse their paychecks.

So far, 102 members of Congress say they will turn down their paychecks during the partial government shutdown, according to social media posts and statements reviewed by CNN. That comprises 20 senators and 82 representatives, with members from both parties making up a similar proportion of those going without pay. Twenty-four representatives and two new senatorspassing on pay are newly elected and were sworn in this year.

While most have asked House Chief Administrative Officer Phil Kiko or Senate financial officials to withhold their pay, others say they plan to donate it to particular charities or causes.

Among them is Sen. Elizabeth Warren, a Massachusetts Democrat who tweeted on New Year's Day -- the day after she announced she would explore a 2020 presidential run -- that she would be donating her paycheck to HIAS, a nonprofit that helps refugees.

Several members of Congress have also pushed legislation that would penalize members for allowing a shutdown to occur. Rep. Kurt Schrader, an Oregon Democrat, introduced a bill in 2017 that would automatically dock members' pay during government shutdowns, and Rep. Ralph Norman, a South Carolina Republican, introduced a constitutional amendment the day before the government shut down that would ban them from being paid.
