The incoming chairman of the House Intelligence Committee this week said that when the new Congress is seated in January, Democrats plan to scrutinize whether President Trump abused his authority by taking adverse action against retail giant Amazon and two of his bitter left-leaning media rivals: CNN and The Washington Post.

Rep. Adam Schiff, D-Calif., said in an interview with “Axios on HBO” that he and his colleagues will employ committee subpoena powers — which are backed by the legal threat of contempt of Congress — to conduct the triple-threaded inquiry into Trump’s possible use of the “instruments of state power to punish the press.”

Specifically, Schiff charged that Trump “was secretly meeting with the postmaster [general] in an effort to browbeat” him into “raising postal rates on Amazon,” whose founder and CEO, Jeff Bezos, separately owns The Washington Post.

“This appears to be an effort by the president to use the instruments of state power to punish Jeff Bezos and The Washington Post,” Schiff said in the interview.

The president signed an executive order earlier this year mandating a review of what he called the “unsustainable financial path” of the United States Postal Service (USPS). And he has reportedly met with Postmaster General Megan Brennan several times to push for hikes to the shipping rates paid by companies like Amazon, although there are no indications he did so to seek political payback.

Trump has long derided the political coverage at the Post, which is fiercely and relentlessly criticial of the White House, as a lobbying tool for Bezos. But he has also feuded specifically with Amazon throughout the year, saying it is taking advantage of taxpayer-subsidized shipping rates.

In March, he argued in a series of tweets that the online retailer’s “scam” shipping deal with the U.S. Postal Service is costing the agency “billions of dollars.”

While the U.S. Postal Service has lost money for 11 years, package delivery — which has been a bright spot for the service — is not the reason. Boosted by e-commerce, the Postal Service has experienced double-digit increases in revenue from delivering packages, but that hasn’t been enough to offset pension and health care costs as well as declines in first-class letters and marketing mail.

Schiff also raised the possibility that the Trump administration’s opposition to AT&T’s $85 billion takeover of Time Warner on antitrust grounds may have been motivated by the president’s animus toward CNN, whose parent company is Time Warner. Trump frequently claims that CNN speads “fake news” and that when it does so, it is acting as the “enemy of the people.”

“We don’t know, for example, whether the effort to hold up the merger of the parent of CNN was a concern over antitrust, or whether this was an effort merely to punish CNN,” Schiff said, without offering evidence.

DEMS TO FLEX MUSCLE WITH NEW HOUSE MAJORITY — IS IMPEACHMENT ON THE TABLE?

“It is very squarely within our responsibility to find out,” Schiff said. Along with incoming House Oversight Committee Chairman Rep. Elijah Cummings, D-Md., and other top Democrats, Schiff will have a mandate to serve a slew of subpoenas on the Trump administration.

But former GOP Judiciary Committee Chairman Jason Chaffetz, who is now a Fox News contributor, told Politico in October that Cummings and Schiff shouldn’t get their hopes up.

“If [North Carolina Rep.] Mark Meadows and [Ohio Rep.] Jim Jordan can’t get documents out of the White House, I don’t know why Elijah Cummings and the Democrats think they’ll do any better,” Chaffetz said.

Still, Democrats had signaled even before last week’s midterm elections that they would aggressively investigate the Trump administration if they took power in Congress. Bogging down the White House with burdensome document requests and subpoenas could indeed backfire, political analysts tell Fox News, but there is little doubt that the strategy — made more viable by heightened partisanship and loosened congressional norms — would impair Republicans’ messaging and even policy goals for the next two years.

“Well, we are responsible,” House Minority leader Nancy Pelosi, who is campaigning to reclaim her role as House speaker, said Sunday on CBS’ “Face the Nation.” “We are not scattershot. We are not doing any investigation for a political purpose, but to seek the truth. So I think a word that you could describe about how Democrats will go forward in this regard is we will be very strategic.”

But Pelosi has previously suggested that she would, indeed, use the threat of subpoenea for political gain.

MAXINE WATERS, SCHIFF TO TAKE HIGH-PROFILE COMMITTEE POSTS IN NEW HOUSE

“Subpoena power is interesting, to use it or not to use it,” Pelosi said at a conference in October, referring to the authority of House committees to summon individuals and organizations to testify or provide documents under penalty of perjury. “It is a great arrow to have in your quiver in terms of negotiating on other subjects.” She added that she would use the power “strategically.” (Trump has flatly called Pelosi’s plan “illegal.”)

Pelosi’s approach would mark the continuation of a trend. Research conducted by Cornell University political science professor Douglas Kriner, who co-wrote the 2016 book “Investigating the President: Congressional Checks on Presidential Power,” underscores the increasingly political nature of House investigations.

“We examined every congressional investigation from 1898 to 2014 – more than 11,900 days of investigative hearings,” Kriner told Fox News. “What we found is that divided government is a major driver of investigations in the House. This is particularly true in periods of intense partisan polarization. For example, from 1981-2014, the House averaged holding 67 days of investigative hearings per year in divided government, versus only 18 per year in unified government.”

Kriner added that modern congressional probes seem geared toward “maximiz[ing] the political damage on the White House,” rather than producing more substantive results. “Investigations are less likely to trigger new legislation than in previous, less polarized eras,” Kriner told Fox News.

On Election Day, Pelosi vowed to “restor[e] the Constitution’s checks and balances to the Trump administration” by enhancing transparency and accountability. But Trump last week signaled he had no patience for that approach, which he characterized as an expensive folly.

“If the Democrats think they are going to waste Taxpayer Money investigating us at the House level, then we will likewise be forced to consider investigating them for all of the leaks of Classified Information, and much else, at the Senate level. Two can play that game!” Trump tweeted.
