McCaskill tweeted that her female Democratic colleagues have discussed the issue and determined that they're "concerned."
"Campaign stress? We think a public daily weigh-in is called for," she added.
The Missouri Democrat then retweeted someone asking if her tweet was a joke, adding, "Yes. Obviously. A pointed one."

McCaskill has remarked on the issue of weight in the past, albeit in personal terms. She announced in 2011 that she had reached a goal of losing 50 pounds and cited Twitter as a way of staying motivated.

She jabbed Trump a day after he doubled down on his critique of former Miss Universe Alicia Machado, who is now supporting Trump Democratic rival, Hillary ClintonHillary Diane Rodham ClintonI voted for Trump in 2020 — he proved to be the ultimate RINO in 2021 Neera Tanden tapped as White House staff secretary Meghan McCain: 'SNL' parodies made me feel like 'laughing stock of the country' MORE.

"She was the worst we ever had," Trump told "Fox & Friends" on Tuesday.
"She was a winner, and she gained a massive amount of weight, and we had a real problem. We had a real problem with her."

Clinton goaded Trump in Monday night's presidential debate, saying he called Machado "Miss Piggy" and "Miss Housekeeping." 

Trump earlier this month remarked on his affinity for fast food when appearing on "The Dr. Oz Show." Mehmet Oz, the show's host, reviewed the results of a recent physical for Trump on the program and said he wasn't worried about the figures.
Trump also released a letter from his doctor this month claiming he was in "excellent physical health." Bloomberg reported that Trump has a body-mass index of about 30, a level that qualifies as obese, according to the Centers for Disease Control and Prevention.

McCaskill's is the second harsh health-related attack directed at the GOP nominee this week.

Howard Dean, a former Democratic National Committee chairman, doubled down on his Monday night insinuation that Trump's debate-night sniffles were related to cocaine use.
