History, demographics and the national mood are pointing to one conclusion about the 2018 congressional races: Democrats are well-positioned to bring one-party government in Washington under Donald Trump’s presidency to a screeching halt. But it's the House, not the Senate, that's most in play.

With a little strategizing, you can avoid surprises when the Republican tax overhaul hits. We are a nation divided by partisanship, but united by befuddlement over the new tax code.

FBI Deputy Director Andrew McCabe has stepped down and will be on leave until he retires sometime in the spring, a person familiar with the matter said Monday. Trump and some Republican lawmakers have alleged that past officials at the Federal Bureau of Investigation, including McCabe, were biased in favor of Democratic Party presidential nominee Hillary Clinton in the run-up to the 2016 election.

Here's how Apple turned itself into a chip superpower. Steve Jobs long believed his company should own the technologies inside its products rather than rely on mashups of components from other chip makers. Today, Apple packs its devices with custom components that process artificial intelligence tasks, track your steps, power game graphics, secure Face ID or Touch ID data, run the Apple Watch, pair AirPods to your phone and help make Macs work the way they do. The result: a chip powerhouse that could one day threaten the dominance of Qualcomm and even, eventually, Intel.
