Input: Consider Input: On Friday  Sen. Dianne Feinstein (D-CA) said she will introduce legislation that would raise the minimum age requirements for purchasing a rifle from a gun dealer.
 Feinstein 's declaration comes after 17 people were killed Marjory Stoneman Douglas High School in Parkland  Florida on Wednesday.
 Feinstein 's proposal received a mixed reaction.
I plan to introduce a bill to require ALL firearms purchases from gun dealers be restricted to individuals who are at least 21 years old. If you can’t buy a handgun or a bottle of beer  you shouldn’t be able to buy an AR-15. — Sen Dianne Feinstein (@SenFeinstein) February 17  2018

Input: Consider Input: JP Morgan's Jamie Dimon  predicts President Donald Trumpâs sweeping tax cut will enable the economy and American businesses to flourish and U.S. workers will be rewarded with hefty pay hikes.
 He  said the tax cut will drive wages higher and spark an economic boom in this country by boosting job creation.
"I think it's possible you're going to hit 4 percent some time this year  " Dimon  told CNBC from the World Economic Forum in Davos  Switzerland.
"I promise you  we are going to be sitting here in a year and you all will be worrying about inflation and wages going up too high "  he  said.
"I can't believe that people think having an uncompetitive tax system is a good thing "  he  added.
 The bank  said Tuesday  it  will spend $20 billion over five years to raise hourly pay for works and open branches in new U.S. locations in the wake of the tax cut.
"We're adding sales people  opening more branches "  he  said. "We think it is good for J.P. Morgan and we think it's going to be very good for the economy."

Input: Consider Input: Callista Gingrich   Nikki Haley  and Scott Brown are all running afoul of federal guidelines on social media while the State Department whistles in the wind.
 US ambassador to the UN Nikki Haley  has  her  staff support  her  personal Twitter account.
 US ambassador to New Zealand Scott Brown  has a gag Twitter account for  his  dog Gracie. And US ambassador-designate to the Vatican Callista Gingrich is tweeting about  her  job before starting in an official capacity. Some of President Donald Trumpâs highest-profile political appointees are running afoul of the governmentâs social media rules  enshrined in the State Departmentâs Foreign Affairs Manual. The rules  pushed through in January after years of internal deliberations  are designed to prevent political appointees from exploiting public office by using their official title to build a massive social media presence and then taking their account with them when they re-enter the private sector or retire. Brown  the short lived former senator from Massachusetts  and Haley  the former governor of South Carolina  both use their personal Twitter accounts for official business alongside their government-owned accounts.
 Haley âs staff also helps service  her  Twitter account  including tasks such as taking photos that are disseminated to  her  more than 770 000 followers.
