(CNN)Republicans on the House Judiciary Committee deleted a tweet Friday morning that spread disinformation about Covid-19 booster shots.
The false tweet from the House Judiciary Committee Republicans' official account, which was posted Thursday afternoon, read: "If the booster shots work, why don't they work?"
The tweet received a wave of backlash before it was taken down and came at a time when Covid cases are spiking across the US following the Omicron variant's emergence, and public health experts are encouraging people to get boosted to protect themselves and others.
While most Republicans have said they support Covid-19 vaccines but oppose mandates, many members of the GOP -- especially those on the far-right -- have continued to spread disinformation, conspiracy theories and anti-vaccine sentiments. Elected Republicans have crusaded against mandates as part of their resistance to the Biden administration's pandemic response efforts.
