Donald Trump lashed out at press coverage of the Republican tax cut package on Thursday morning, saying 'fake news' media is doing the Democrats' bidding by writing critically about it.

A bill lowering income taxes for 80 per cent of Americans sits on his desk after the Senate passed it Tuesday night and the House of Representatives gave its final approval Wednesday morning.

But Trump is still angling for his pound of flesh.

'The Massive Tax Cuts, which the Fake News Media is desperate to write badly about so as to please their Democrat bosses, will soon be kicking in and will speak for themselves,' he tweeted on Thursday.

'Companies are already making big payments to workers. Dems want to raise taxes, hate these big Cuts!'

President Donald Trump came out swinging Thursday against critics of the Republican tax cut plan, including 'fake news' media whom he sees as water-carriers for angry Democrats

Wednesday's White House victory lap highlighted the first major federal income tax cut in more than 30 years

The president was ebullient on Wednesday but returned to attack mode a day later

True enough, a handful of giant U.S. corporations pledged Wednesday to deliver bonuses to hundreds of thousands of U.S. employees.

Their tax rate will drop from 35 per cent to 21 per cent in a matter of months, a move that Trump called 'rocket fuel' for the nation's economy on Wednesday.

AT&T said it will pay $1,000 bonuses to more than 200,000 workers, and promised to make $1 billion in new investments in the United States in 2018.

Comcast NBCUniversal said it would award $1,000 bonuses to more than 100,000 employees.

Fifth Third Bancorp in Cincinnati, Ohio said it will pay $1,000 bonuses to more than 13,500 employees and raise the minimum wage for its workforce to $15 per hour because its tax rate is about to plummet.

Wells Fargo matched that $15 per hour minimum wage hike and said it was prompted by the tax plan. The San Francisco-based bank also said it would make $400 million in donations to nonprofit charities and other community organizations in 2018.

Boeing said it would make a '$300 million employee-related and charitable investment as a result of #TaxReform legislation.'

Trump also praised 'Fox & Friends' after its trio of hosts were named as the most influential people in media in an annual survey

'Fox & Friends' co-hosts (L-R) Steve Doocy, Ainsley Earhardt and Brian Kilmeade have become TV rock stars since the President of the United States began regularly praising their show

Trump's tax-cut speech at the White House included the news that AT&T is responding by paying $1,000 bonuses to all its workers, a message he pushed Thursday as well

FedEx also showed optimism, with its CFO saying during an earnings call that the package shipping giant will likely expand if the tax cuts lead to larger national economic growth.

But the president's chief complaint on Thursday was with the national press corps, which in large part made his argument for him with skeptical headlines and coverage.

'Enjoy your tax cuts while they last,' an NBC News headline blared, forecasting a day in 2025 when this week's individual tax cuts expire unless political pressure drives Congress to renew them.

The New York Times gave its readers a feature article about 'how the "small-business tax cut" would also be a tax cut for the wealthy.'

And The Washington Post reacted to the rare Washington tax relief with a story about how 'Trump stands to save millions' personally.

Trump didn't single out the morning cable TV news shows he loves to hate, including MSNBC's 'Morning Joe' and CNN's 'New Day.'

In a letter to employees, AT&T CEO Randall Stephenson said the bonuses would be paid to all 'union-represented, non-management, and 1st and 2nd line managers'

Big busness follows: Comcast, which also owns NBC Universal, announced $1,000 each for more than 100,000 staff, Boeing said it would put $300 million into workforce development and Wells Fargo hiked its minimum wage to $15 an hour

But he did go out of his way to praise the Fox News Channel's daily offering after the Mediaite website named its trio of hosts #1 on a list of the most influential people in media.

'Was @foxandfriends just named the most influential show in news? You deserve it – three great people!' the president tweeted.

'The many Fake News Hate Shows should study your formula for success!'

AT&T's dramatic move on Wednesday underscored what the White House hopes will be a quick race to economic expansion under the new tax regime.

President Trump posted two pictures to his Instagram Wednesday evening, including this one of himself in the Oval Office with Vice President Mike Pence (right), Senate Majority Leader Mitch McConnell (left) and House Speaker Paul Ryan (2nd left)

Trump's event on the White House's South Lawn was attended by nearly all the Republican members of Congress; 12 House members who voted against it stayed back along with one senator, Jeff Flake, who has feuded with Trump all year

In a letter to employees, the telecom company's CEO Randall Stephenson said the bonuses would be paid to all 'union-represented, non-management, and 1st and 2nd line managers.'

'If the President signs the bill before Christmas, employees will receive the bonus over the holidays,' he added.

Just minutes before AT&T announced its employee bonuses, Senate Minority Leader Chuck Schumer excoriated the company as a greedy corporation that would use its tax cut to buy back its stock and reward its executives.

'Over the last ten years, AT&T has paid an average tax rate of 8 per cent a year. They have 80,000 fewer employees today than they had then,' the New York Democrat complained.

'Tax breaks don't lead to job creation. They lead to big CEO salaries and money for the very, very wealthy.'
