Rubio made eight floor speeches this year, only two of which came after he launched his presidential campaign in April, and showed up for 64 percent of the votes. The Florida lawmaker has been criticized by Republican primary rivals for his poor attendance record.
Sen. Bernie Sanders (I-Vt.) set the pace for senators when it came to delivering floor speeches, giving 37 throughout the year. He also attended 91 percent of the votes in the upper chamber.
Although he only spoke 13 times, Sen. Rand Paul (R-Ky.) had the highest attendance record, making 94 percent of the votes.
Paul called for Rubio to resign from Congress over his missed vote on the government spending bill earlier this month.
Rubio defended his absence from the omnibus vote, saying, “Not voting for it is a vote against it.”
In an interview on Fox News's "On the Record" on Tuesday, Rubio said he didn't show up for the vote on the omnibus because "the outcome was predetermined."
"They went behind closed doors, they cut this deal, they sprung it on everybody saying 'take it or leave it vote,'" he said. "The outcome was predetermined. I'm running for president so this never happens again."
Sen. Lindsey Graham (R-S.C.), who suspended his presidential campaign on Monday, spoke 16 times and showed up for 71 percent of the votes.
