President Trump suggested Monday that his anti-government corruption mantra of “draining the swamp” already needs an overhaul.

“Drain the Swamp should be changed to Drain the Sewer – it’s actually much worse than anyone ever thought, and it begins with the Fake News!” the president tweeted.

“After 1 year of investigation with Zero evidence being found, Chuck Schumer just stated that ‘Democrats should blame ourselves, not Russia,’” he added in a separate tweet.

During an appearance on ABC’s “This Week,” Sen. Schumer discussed the Democrats’ new economic agenda, which he said they would present Monday.

“The No. 1 thing that we did wrong is we didn’t tell people what we stood for,” Schumer said.

Trump’s tweets came shortly after his son-in-law and senior adviser Jared Kushner released a statement ahead of his closed-door testimony to a Senate committee probing Russia’s meddling in the 2016 election and any possible collusion by Trump associates.

A couple of hours later, Trump continued his tweetstorm about the Russia investigation, asking why the congressional panels probing Russia aren’t examining Hillary Clinton’s role.

“So why aren’t the Committees and investigators, and of course our beleaguered A.G., looking into Crooked Hillarys crimes & Russia relations?,” he wrote Monday morning.

He then criticized Rep. Adam Schiff, the ranking Democrat on the House Intelligence Committee, for appearing on TV news shows to talk about the probes.

​”Sleazy Adam Schiff, the totally biased Congressman looking into ​’​Russia,​’​ spends all of his time on television pushing the Dem loss excuse!​,” Trump tweeted.​

Trump has said the Democrats made up Russian involvement in the election because they are upset that he beat Clinton ​in November.

Then Trump turned to the effort to overhaul ObamaCare, which the Senate is expected to vote on this week.

​”​Republicans have a last chance to do the right thing on Repeal & Replace after years of talking & campaigning on it​,” he wrote.​
