President Donald Trump on Wednesday used his tax-reform pitch in Missouri to make the case for a 15% corporate tax rate as he said he would help Texas recover from devastating floods.

MISSOURI TAX PITCH

Trump went to the Show-Me State in part because he thinks he can win the support of Sen. Claire McCaskill, the Democratic senator from Missouri, a state Trump carried easily in the presidential election. “If she doesn’t do it for you, you have to vote her out of office,” Trump said.

One unexpected development was Trump stating he wanted a 15% corporate tax rate. White House officials had indicated he wasn’t going to go into details, as it’s leaving it up to Congress to write a tax plan after articulating principles. A corporate tax rate that low — the current rate is 35%, though there a number of loopholes companies can exploit to lower their payments — would make it challenging to create a plan that is deficit neutral, which it would have to be to pass in the Senate with only Republican votes.

The undercurrent of Trump’s pitch was his disappointment that Republicans have not been able to repeal Obamacare. “I don’t want to be disappointed by Congress, do you understand me?” Trump said.

TOUTING GDP

Trump did tout the latest data to come out of the Commerce Department, showing an upward revision to 3% growth in the second quarter.

“We announced we had 3% in GDP, it just came out. On the yearly basis, the last administration never hit 3%,” Trump said. “We are really on our way.”

MESSAGE TO TEXAS

Trump started his speech by talking about the rain which has flooded Houston and other communities. “We are with you today, we are with you tomorrow, and we will be with you every single day after, to restore, recover and rebuild,” he said.

He also sent a tweet along the same lines.

Reporters noted that Trump did not meet any hurricane victims during his visit to Texas on Tuesday.

NO DIPLOMACY FOR NORTH KOREA

Also noteworthy on the Twitter front, Trump tweeted that the U.S. has been talking to North Korea “and paying them extortion money” for 25 years, which he said wasn’t the answer.

Another tweet spoke of the “ferocious anger” in magazines, a possible reference to unflattering covers of periodicals including The New Yorker, Time and Der Spiegel. “After reading the false reporting and even ferocious anger in some dying magazines, it makes me wonder, WHY? All I want to do is #MAGA!,” he tweeted.
