Washington (CNN)After teasing reporters earlier Friday that he was set to reveal his presidential ambitions for 2016, former Arkansas Gov. Mike Huckabee went on Fox News to instead say that he will announce his plans in his home state next month.

"Come to Hope on May the 5th. You'll find out what's going to happen," Huckabee told Bret Baier on "Special Report" Friday night. "I think it'll be worth tuning in for."

The current tax code taxes too much, taxes unfairly, and conspires with our outmoded welfare system to trap poor families in poverty, rather than facilitate their climb into the middle class. Our reforms seek to simplify the structure and lower rates. How? By consolidating the many existing income tax brackets into two simple brackets—15% and 35%—and eliminating or reforming deductions, especially those that disproportionately benefit the privileged few at everyone else’s expense.

Sen. Ted Cruz (R-TX) believes the IRS should be abolished after the institution of a simpler flat tax.
He said the tax code invites agents to abuse and use the machinery of government to target political enemies and said doing so was wrong whether the president was Barack Obama or Richard Nixon.

“I think we ought to abolish the IRS and instead move to a simple flat tax,” Cruz said on Fox News over the weekend.

He said the tax code should be simple enough for the average American to fill out on a postcard.

Ben Carson will make a major announcement on his 2016 presidential-campaign plans in three weeks, CNN reported Monday night, citing a spokeswoman.

But while the network reported that the speech will be made May 4 in Detroit, spokeswoman Deanna Bass cautioned that her boss, the first major Republican to start a presidential exploratory committee back in February, may either run or not run.

Rubio’s frustration with the Senate, long an open secret among his colleagues, has personal and political aspects. The freshman lawmaker “feel[s] guilty” about the amount of time he spends away from his young family in Miami, as he wrote in his memoir. The job doesn't pay particularly well relative to what Rubio could make in the private sector. Democrats have thwarted most of his major legislative efforts, and his one big attempt to reach across the aisle, the Gang of Eight immigration bill, cost him support among the same tea-party voters who had swept him into office.

WASHINGTON — Sen. Marco Rubio of Florida, a telegenic rising star with appeal to conservative and establishment Republicans, told donors in a conference call today that he will run for president, according to multiple news reports.
