Nadler was responding to reports that President Trump won't reimburse health insurers for covering low income people as a way of forcing Democrats to the negotiating table on health care.
The long-distance razzing comes after Trump suggested over the weekend that the media were playing up the Georgia election just like they did with last week's special election in Kansas, "until the Republicans won".
The candidates to replace Price include Ossoff and several Republicans, former Georgia Secretary of State Karen Handel, businessman Bob Gray and former state Sens.
If Ossoff captures 50 percent in the primary, which is crowded with 18 contenders, he will avoid a June runoff with a Republican candidate.
The Opinion Savvy poll conducted for FOX 5 shows Democrat Ossoff leading the race at 42percent, followed by former Georgia Secretary of State Handel at 21 percent.
"While I'm glad the President is interested in the race, he is misinformed", he said in a statement.
"The recent Kansas election (Congress) was a really big media event, until the Republicans won", the president tweeted.More news: Inmates begin hunger strike on Palestinian Prisoners' Day
"I don't care what party you're from", said Marty Aftewicz, a 66-year-old Republican voter from Marietta.
On Tuesday, Republican Ron Estes was elected by seven percentage points to represent the 4th, which five months ago Donald Trump won by 27 points and then-incumbent congressman Mike Pompeo, now director of the Central Intelligence Agency, took by 31 points.
Trump and House GOP leaders failed stunningly last month to pass their ObamaCare repeal proposal in the face of opposition from both conservative and centrist Republicans. All candidates run on one ballot for the election, which is set for Tuesday.
Democrats haven't won this House seat - which was occupied for 20 years by former House Speaker Newt Gingrich - since 1976. National Republicans have tried to blunt his financial advantage, pouring more than $4 million of their own money into the race to try to tear Ossoff down, claiming he's embellished his resume and would vote in lock-step with national Democrats. "And Jon, to me, represents fresh, young, moderate blood that we need in Washington, and I'd like to see more young people with fresh ideas get there". Ossoff, meanwhile, said he would seek to help improve Obamacare and generally delivered a fairly traditional Democratic message, with a dose of fiscal conservatism.
Ossoff has raised an astonishing $8 million, mostly from outside the state. Anyone sending a contribution would be rewarded with a "free "I support Donald Trump" bumper sticker", it said.
Party strategists, however, say the drop-off was harmful but understandable: Democrats grew complacent with President Barack Obama in office, while Republicans - incited by his performance in the White House - grew angry.
The back-and-forth between Trump and Ossoff reflects the overall narrative of the whirlwind campaign since Price's Cabinet confirmation.
